A problem common to both state of-the-art approaches to integrated circuit fabrication is that of miniaturizing and intGgrating inductors. It is found that, for a certain range of injection current levels, certain unsymmetrically doped junction diodes have an inductive small-signal impedance. This thesis discusses the theor,y of inductance diodes and applies finite difference equations and the Linvill lumped model to the differential equations that describe their carrier nov.r processes. -

Particularly our increasing ability to manxifac- ture reproducible transistors has brought us to the point of designing circuits for specific application to tran- sistors, not just to illustrate the application but rathei* •ngineered to rigid specifications. This paper treats Just such a design, that of obtaining automatic gain control of a transistor amplifier. There has been as yet little published about this difficult problem, and much of the work here presented is believed to be original* The majority of the experimental work connected with this thesis was performed during the author's Industrial Experience Tour while at Lenkurt Electric Company, San Carlos, California, and he is indebted to them for their cooperation and assistance. -
Low Noise Dual Gate Enhancement Mode MOSFET with Quantum Valve in the Channel
Proceedings of the World Congress on Electrical Engineering and Computer Systems and Science (EECSS 2015) Barcelona, Spain, July 13-14, 2015 Paper No. 153 Low Noise Dual Gate Enhancement Mode MOSFET with Quantum Valve in the Channel Sam Halilov, Anass Dahany, Sam Mil’shtein University Ave 1, University of Massachusetts Department of Electrical and Computer Engineering Lowell, MA 01854, USA Abstract- A proposed Si-based series multi-gate E-MOSFET is discussed in terms of its design, static and dynamic transport properties and noise figure. In its simplest realization, the design involves two gates in series comprising an extra n(p)-doped junction in the p(n)-channel. The role of the nano-scale junction is twofold: to minimize the Miller effect in the enhancement mode to improve the frequency response and to create a quantum well to quench the current noise associated with the carrier velocity fluctuations. While dual-gate depletion structure results in a reduced carrier transition time along the entire channel path, the quantization effects serve as a current noise filter. Similar quantum valve can be realized in the form of a well both in n- and p-channel enhancement mode FET, whereas the majority carriers experience a tunneling through a similar shape barrier. Doping concentration and size of the middle junction are free parameters and can be adjusted to the required figures of merit. AC device simulations confirm the expectations based on the along-the-channel potential profile: enhanced cutoff frequency and higher saturation current are the signatures of the reduced transition and RC-time, whereas the minimum noise figure and transfer functions demonstrate noise filtering capabilities of the state quantization. -

Overload Protection
Overload Protection Before discussing specific control components, it is necessary to review what an overload is and what steps can be taken to limit the damage an overload can cause. Current and Temperature Current flow in a conductor always generates heat due to resistance. The greater the current flow, the hotter the conductor. Excess heat is damaging to electrical components. For that reason, conductors have a rated continuous current carrying capacity or ampacity. Overcurrent protection devices are used to protect conductors from excessive current flow. Thermal overload relays are designed to protect the conductors (windings) in a motor. These protective devices are designed to keep the flow of current in a circuit at a safe level to prevent the circuit conductors from overheating. 22 Excessive current is referred to as overcurrent. The National Electrical Code® defines overcurrent as any current in excess of the rated current of equipment or the ampacity of a conductor. It may result from overload, short circuit, or ground fault (Article 100-definitions). Short Circuits When two bare conductors touch, a short circuit occurs. When a short circuit occurs, resistance drops to almost zero. Short- circuit current can be thousands of times higher than normal operating current. Ohm’s Law demonstrates the relationship of current, voltage, and resistance. For example, a 240 volt motor with 24 ohms of resistance would normally draw 10 amps of current. When a short circuit develops, resistance drops. If resistance drops to 24 milliohms, current will be 10,000 amps. The heat generated by this current will cause extensive damage to connected equipment and conductors. -
