Currently, multi-band coexistence is enabled by a network of discrete, off-chip com- ponents that are bulky, expensive, and narrowband. As transceivers are required to accom- modate an increasing number of wireless bands, the required number of discrete components increases accordingly, resulting in greater bill of materials (BoM) cost and front-end module (FEM) area.

As my grandfather would have said. iii iv Abstract The wireless market is developing very fast today with a steadily increasing num- ber of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. As a result there is a huge demand for flexible and low-cost radio architectures for portable applications. Moving towards multi- standard radio, a high level of integration becomes a necessity and can only be ac- complished by new improved radio architectures and full utilization of technology scaling. Modern nanometer CMOS technologies have the required performance for making high-performance RF circuits together with advanced digital signal processing.

Mortensen 2018 SIGNATURE PAGE THESIS: ANALYSIS AND DESIGN OF AN RF FRONT END FOR A RADAR DIGITAL RECEIVER AUTHOR: John O. Mortensen DATE SUBMITTED: Winter 2018 Electrical and Computer Engineering Department Dr. James Kang Thesis Committee Chair Electrical Engineering Dr. Thomas Ketseoglou Electrical Engineering Dr. Saloman Oldak Electrical Engineering ii ACKNOWLEDGEMENTS First, I’d like to thank my adviser Dr. James Kang for the patient help he has provided over the two years of my pursuit of my master’s degree. In addition I’d like to thank Dr. Ketseoglou and Dr. Oldak and the rest of the staff at Cal Poly for all of the great electronics courses I’ve taken both recently and back in the 1980s when I first received my BSEE. I’d should also thank MPT and its owner Dr. Rick Sturdivant for the help on this project and the funding available to complete this research and project. I’d also like to thank my wife Marie for putting up with me and the support she has given me over the years. iii ABSTRACT This paper focuses on the use of commercial off the shelf parts in the design of an X Band receiver used in radar. The need today for a low cost flexible approach is of the utmost importance due to the trend of having a transceiver module for each element of a phased array antenna.

  • Programmable and Tunable Circuits for Flexible RF Front Ends
    Linköping Studies in Science and Technology Thesis No. 1379 Programmable and Tunable Circuits for Flexible RF Front Ends Naveed Ahsan LiU-TEK-LIC-2008:37 Department of Electrical Engineering Linköping University, SE-581 83 Linköping, Sweden Linköping 2008 ISBN 978-91-7393-815-0 ISSN 0280-7971 ii Abstract Most of today’s microwave circuits are designed for specific function and special need. There is a growing trend to have flexible and reconfigurable circuits. Circuits that can be digitally programmed to achieve various functions based on specific needs. Realization of high frequency circuit blocks that can be dynamically reconfigured to achieve the desired performance seems to be challenging. However, with recent advances in many areas of technology these demands can now be met. Two concepts have been investigated in this thesis. The initial part presents the feasibility of a flexible and programmable circuit (PROMFA) that can be utilized for multifunctional systems operating at microwave frequencies. Design details and PROMFA implementation is presented. This concept is based on an array of generic cells, which consists of a matrix of analog building blocks that can be dynamically reconfigured. Either each matrix element can be programmed independently or several elements can be programmed collectively to achieve a specific function. The PROMFA circuit can therefore realize more complex functions, such as filters or oscillators. Realization of a flexible RF circuit based on generic cells is a new concept. In order to validate the idea, a test chip has been fabricated in a 0.2µm GaAs process, ED02AH from OMMICTM. Simulated and measured results are presented along with some key applications like implementation of a widely tunable band pass filter and an active corporate feed network.

    Vol. 31, No. 2 Journal of Semiconductors February 2010 Noise-canceling and IP3 improved CMOS RF front-end for DRM/DAB/DVB-H applications Wang Keping(王科平)1, Wang Zhigong(王志功)1; 2; , and Lei Xuemei(雷雪梅)1 (1 Institute of RF- & OE-ICs, Southeast University, Nanjing 210096, China) (2 Engineering Researching Center of RF-ICs & Systems of the Ministry of Education of China, Southeast University, Nanjing 210096, China) Abstract: A CMOS RF (radio frequency) front-end for digital radio broadcasting applications is presented that con- tains a wideband LNA, I/Q-mixers and VGAs, supporting other various wireless communication standards in the ultra- wide frequency band from 200 kHz to 2 GHz as well. Improvement of the NF (noise figure) and IP3 (third-order in- termodulation distortion) is attained without significant degradation of other performances like voltage gain and power consumption. The NF is minimized by noise-canceling technology, and the IP3 is improved by using differential mul- tiple gate transistors (DMGTR). The dB-in-linear VGA (variable gain amplifier) exploits a single PMOS to achieve exponential gain control. The circuit is fabricated in 0.18-m CMOS technology. The S11 of the RF front-end is lower than 11:4 dB over the whole band of 200 kHz–2 GHz. The variable gain range is 12–42 dB at 0.25 GHz and 4–36 dB at 2 GHz. The DSB NF at maximum gain is 3.1–6.1 dB. The IIP3 at middle gain is 4:7 to 0.2 dBm. It consumes a DC power of only 36 mW at 1.8 V supply.
