Cum Laude for PhD student Huajun Zhang
- Wednesday, 24 April 2024
On April 15 PhD student Huajun Zhang (EI group) promoted Cum Laude.
High-performance multilevel Class-D audio amplifiers.
Abstract: Despite their high power efficiency, Class-D amplifiers (CDAs) suffer from greater EMI, inferior linearity, and lower DR than Class-AB amplifiers. This thesis describes the design and implementation of CDAs that aim to approach the performance of Class-AB amplifiers in terms of their application cost, dynamic range, and linearity while retaining the characteristic high power efficiency of the CDA, through the use of a multilevel output stage, feedback after the LC filter, and capacitive feedback. Measurement results from prototypes showed state-of-the-art performance.
