WANG, Junjie (author)AC-coupled amplifiers (ACCA) offer lower noise than traditional resistor feedback amplifiers, which benefits signal-to-noise ratio (SNR) for audio applications. Due to the DC isolation of the capacitor, a feedback resistor is needed to set the virtual ground of ACCA’s amplifier. However, an external feedback resistor raises system noise and...master thesis 2023

Lombardo, Nick (author)Class-D amplifiers are quickly becoming the standard in many audio applications. Their highly efficient behavior and wide power range make these amplifiers more suitable than traditional Class A/AB audio amplifiers. Battery-powered devices are a particularly interesting sub-field due to their special demand for extended battery duration and...master thesis 2022

Zhang, Miao (author)Class-D amplifiers are widely used in automotive audio systems because of their high efficiency. In modern car sound systems, multiple amplifiers are used to provide good audio effect. However, typical class-D amplifiers have a high idle-power, which can drain the battery quickly. To solve this problem, an ultra-low idle power class-D amplifier...master thesis 2019
