A Temperature and Process Insensitive Cmos Only Reference
A TEMPERATURE AND PROCESS INSENSITIVE CMOS ONLY REFERENCE CURRENT GENERATOR A Thesis Presented to The Graduate Faculty of The University of Akron In Partial Fulfillment of the Requirements for the Degree Master of Science Shivasai Bethi December, 2014 A TEMPERATURE AND PROCESS INSENSITIVE CMOS ONLY REFERENCE CURRENT GENERATOR Shivasai Bethi Thesis Approved: Accepted: ________________________ ________________________ Advisor Department Chair Dr. Kye-shin Lee Dr. Abbas Omar ________________________ ________________________ Committee Member Dean of the College Dr. Joan E. Carletta Dr. George K. Haritos ________________________ ________________________ Committee Member Interim Dean of the Graduate School Dr. Robert Veillette Dr. Rex D. Ramsier ________________________ Date ii ABSTRACT This thesis presents the design of a temperature and process insensitive CMOS only reference current generator. The proposed reference current generator consists of a conventional CMOS Widlar current source, in which the passive resistor is replaced with a transistor resistor. The gate voltage of the transistor resistor is provided by a gate bias generator that makes the output current insensitive to temperature variation. Furthermore, to achieve a process insensitive reference current, three separate gate bias generator circuits for nominal, strong and weak corners were designed. These gate bias generators are manually selected by the control switches to minimize the current variation under different process corners. As an extension of the manual mode selector, the design of an automatic mode selector that automatically selects the optimum gate bias generators to minimize the current variation under different process corners is realized. The proposed reference current generator can be used for high temperature sensor interface applications that include amplifiers, oscillators, filters and data converters. -
Few-Electron Ultrastrong Light-Matter Coupling in a Quantum LC Circuit
PHYSICAL REVIEW X 4, 041031 (2014) Few-Electron Ultrastrong Light-Matter Coupling in a Quantum LC Circuit Yanko Todorov and Carlo Sirtori Université Paris Diderot, Sorbonne Paris Cité, Laboratoire Matériaux et Phénomènes Quantiques, CNRS-UMR 7162, 75013 Paris, France (Received 19 March 2014; revised manuscript received 23 October 2014; published 18 November 2014) The phenomenon of ultrastrong light-matter interaction of a two-dimensional electron gas within a lumped element electronic circuit resonator is explored. The gas is coupled through the oscillating electric field of the capacitor, and in the limit of very small capacitor volumes, the total number of electrons of the system can be reduced to only a few. One of the peculiar features of our quantum mechanical system is that its Hamiltonian evolves from the fermionic Rabi model to the bosonic Hopfield model for light-matter coupling as the number of electrons is increased. We show that the Dicke states, introduced to describe the atomic super-radiance, are the natural base to describe the crossover between the two models. Furthermore, we illustrate how the ultrastrong coupling regime in the system and the associated antiresonant terms of the quantum Hamiltonian have a fundamentally different impact in the fermionic and bosonic cases. In the intermediate regime, our system behaves like a multilevel quantum bit with nonharmonic energy spacing, owing to the particle-particle interactions. Such a system can be inserted into a technological semi- conductor platform, thus opening interesting perspectives for electronic devices where the readout of quantum electrodynamical properties is obtained via the measure of a DC current. -

Introduction In Lecture 3 we completed the foundations of Dirac-notation quantum mechanics. Today we'll begin our study of the quantum harmonic oscillator, which is the quantum system that will pervade the rest of our semester's work. We'll start with a classical physics treatment and|because 6.453 is an Electrical Engineering and Computer Science subject|we'll develop our results from an LC circuit example. Classical LC Circuit Consider the undriven LC circuit shown in Fig. 1. As in Lecture 2, we shall take the state variables for this system to be the charge on its capacitor, q(t) Cv(t), and the flux through its inductor, p(t) Li(t). Furthermore, we'll consider≡ the behavior of this system for t 0 when one≡ or both of the initial state variables are non-zero, i.e., q(0) = 0 and/or≥p(0) = 0. You should already know that this circuit will then undergo simple6 harmonic motion,6 i.e., the energy stored in the circuit will slosh back and forth between being electrical (stored in the capacitor) and magnetic (stored in the inductor) as the voltage and current oscillate sinusoidally at the resonant frequency ! = 1=pLC. -

Experiment 2: Discrete BJT Op-Amps (Part I)
EE 140 ANALOG INTEGRATED CIRCUITS SPRING 2011 C. Nguyen Experiment 2: Discrete BJT Op-Amps (Part I) This is a three-week laboratory. You are required to write only one lab report for all parts of this experiment. 1.0. INTRODUCTION In this lab, we will introduce and study the properties of a few circuit blocks commonly used to build operational amplifiers. Because we are limited to using discrete components, we will not be able to construct a complete op-amp. This will be done in the op-amp design project later in the semester. In this lab, however, we will ask you to analyze and design circuits commonly used to make integrated circuit operational amplifiers, and you will use these circuits to build a differential amplifier with both resistive and current mirror biasing. Although built with discrete devices, this op-amp uses a classical topology common to most commercial op- amps including the well-known 741. The operation of these circuits will depend on the use of matched transistors. The CA3083 is a matched NPN transistor array built on a single integrated substrate. To ensure that the transistors are properly isolated, you must connect pin 5 of the array to the most negative point of the circuit (-6 volts). Data sheets for the CA3083, and discrete npn and pnp transistors needed in this lab are attached. In this lab more than any other so far, neatness counts. Unless you build your circuits neatly, they will not operate. Trim your resistor leads if necessary. Make sure that you record all the measurements that you make as you proceed, and include these measurements in your lab report. -

Pfeiffer1, I. L. Egusquiza2, M. Di Ventra3, M. Sanz1 & E. Solano1,4 Technology based on memristors, resistors with memory whose resistance depends on the history of the crossing charges, has lately enhanced the classical paradigm of computation with neuromorphic architectures. However, in contrast to the known quantized models of passive circuit elements, such Received: 22 March 2016 as inductors, capacitors or resistors, the design and realization of a quantum memristor is still missing. Here, we introduce the concept of a quantum memristor as a quantum dissipative device, whose Accepted: 17 June 2016 decoherence mechanism is controlled by a continuous-measurement feedback scheme, which accounts Published: 06 July 2016 for the memory. Indeed, we provide numerical simulations showing that memory effects actually persist in the quantum regime. Our quantization method, specifically designed for superconducting circuits, may be extended to other quantum platforms, allowing for memristor-type constructions in different quantum technologies. The proposed quantum memristor is then a building block for neuromorphic quantum computation and quantum simulations of non-Markovian systems. Although they are often misused terms, the difference between information storage and memory is relevant. While the former refers to saving information in a physical device for a future use without changes, a physical sys- tem shows memory when its dynamics, usually named non-Markovian1,2, depend on the past states of the system. -

Current Mirrors
Current mirrors Current mirrors are important blocks in electronics. They are widely used in several applications and chips, the operational amplifier being one of them. Current mirrors consist of two branches that are parallel to each other and create two approximately equal currents. This is why these circuits are called current mirrors. These currents are used to load other stages in circuits and they are designed in such a way so that current is constant and independent of loading. Current mirrors come in different varieties: Simple current mirror (BJT and MOSFET) Base current corrected simple current mirror Widlar current source Wilson current mirror (BJT and MOSFET) Cascoded current mirror (BJT and MOSFET) For best performance, transistors should be matched, temperature should be the same for all devices and collector-base/drain-gate voltages should also be matched. This will provide equal currents on both sides of the current mirror. All of the circuits have a compliance voltage which is the minimum output voltage required to maintain correct circuit operation: the BJT should be in the active/linear region and the MOSFET should be in the active/saturation region. 1 www.ice77.net Simple current mirror Two implementations exist for the simple current mirror: BJT and MOSFET. BJT The BJT implementation of the simple current mirror is used as a block in the operational amplifier.
