Advanced Class-D audio amplifier

Audio amplifiers can be found in many places such as cell phones, laptops, automobiles, theatres and etc. In this project, we will focus on high-power audio amplifiers (>100W) for high-end audio applications. We can take advantage of GaN technology which offers high efficiency and switching frequency at high operating current and also the standard silicon CMOS technology for sophisticated control optimization. You will learn to design circuits in both GaN and silicon technology and build your own super audio system!

Assignment

The following project activities are expected:

·         Comprehensive literature study

·         System-level behaviour model

·         Transistor-level circuit design

·         A tapeout is highly encouraged

·         Thesis writing

Requirements

You are an ambitious master student with good analog circuit design knowledge and high motivation. You should have obtained good grades from the following courses: Measurement and instrumentation, Analog circuit design fundamentals, CMOS I/II, Power conversion in CMOS technology.
