A Single Chip 1 W CMOS Audio Power Amplifier with Pseudo Buffer Analog and Class D Switching Mixed Mode for Mobile Application
Summary :
A single chip analog and class D switching mixed mode audio power amplifier using 0.35 µm CMOS process is presented in this paper. It has on-chip power MOSFET's and adopts a novel reverse recovery current free gate control that can reduce EMI noise and current stress of the power MOSFET's. It shows about 0.1% THD at 1 kHz and up to 87% efficiency at 4 Ω BTL at 3.3 V single power supply.
