ECE266/466: RF/Microwave Integrated Circuits

This course involves the analysis and design of radio-frequency (RF) integrated circuits at the transistor level. We begin with an introduction to radio architectures and specifications. After discussion of RLC networks, high-frequency amplifiers are studied, followed by wideband amplifiers. Then we examine the important issue of noise with the design example of low-noise amplifier (LNA). Nonlinear circuits are studied next with the example of mixers, followed by oscillators and the important subject of phase noise. Then we introduce phase-locked loops and frequency synthesizers. A study of RF power amplifiers follows, and the course concludes with an overview of transceivers. The course emphasizes the development of both circuit design intuition and analytical skills. There are bi-weekly design labs and a term project using industry-standard EDA tools (ADS, Asitic, Cadence).

ECE269/469: High-Speed Solid-State Electronics

This is an introduction course for state-of-the-art integrated electronics in high-speed/wideband applications, which spans the fields of wireless communications, computing, fiber optics, and instrumentation. We begin with an overview of high-speed semiconductor technologies (CMOS, SiGe, SOI, GaAs, InP, and SiC/GaN) and devices (MOSFET, MESFET, HEMT, HBT, and tunneling diodes), followed by discussion of device characterization and technology optimization for circuit performance. In the second part of the course, we focus on the design of wideband and/or high-power amplifiers, which includes discussions on feedback, impedance matching, distributed amplifiers, power combining, and switching power amplifiers. The third part of the course involves the design of high-speed phase-locked loops (PLL), including delay-locked loops (DLL). After a review of PLL basics, we discuss its building blocks: VCO, frequency divider, phase detector, and loop filter. We also analyze its performance, in particular phase noise (a.k.a. jitter) and dynamic performance, and how to improve them. Two important applications, frequency synthesis and clock recovery, serve as the examples in our discussion. Each part of the course also includes related simulation methods and measurement techniques. The course emphasizes the understanding of basic circuit operation, and the development of circuit design intuition.
