Radio Frequency Integrated Circuits
This course covers the design of radio-frequency integrated circuits (RFICs) used for wireless communications, and it emphasizes both theoretical and practical RF circuit design techniques, spanning from architectural considerations to transistor-level circuit design. It begins with fundamental RF design concepts, including harmonic distortion, noise, and impedance transformation, and proceeds to explore transceiver architectures, with a significant emphasis on low-noise amplifiers and mixer design. The course also includes lectures on the basics of oscillators.
Special Topics in Electronics
This course focuses on advanced topics in wireless communications from both system and circuit viewpoints. It covers the basics of in-band full duplex transceivers and self-interference cancellation methods, phased arrays and the concept of inter-channel interference in simultaneous transmit and receive (STAR) phased arrays, design of phased locked loops (PLL) and synthesizers, as well as basics of power amplifiers. It also includes advanced topics on circuit design such as noise cancellation techniques in LNAs, design of harmonic rejection mixers, and design of injection-locking and low-phase-noise oscillators.
Electronics III
This course begins with reviewing DC characteristics and basics of single and multi-stage amplifiers and approaches to introducing frequency dependent model of transistors and analyzing the frequency response of amplifiers. It covers pole-zero calculation, Bode plots, time-constant methods, feedback concepts, stability analysis, and frequency compensation methods for amplifiers. It ends up with design of an OpAmp with certain specifications and verifying its performance through simulations.
Electronics II
This course contains a review of BJT and MOSFET physics, deriving their small signal models, and analyzing DC characteristics, input/output resistances, and gain of single-stage amplifiers. It then covers the ins and outs of differential pairs, current mirrors, active loads, output stages, and passive feedbacks. It also includes the design of telescopic, low-voltage, and folded cascode CMOS amplifiers.
