摘要
Abstract
An new type of adjustable POP noise suppression system is designed for integrating in the chip, and providing a stable POP noise suppression. By using SMIC 0. 18 μm CMOS fabrication,this device is focusing on the use of a timing control method to make the Class D power amplifier op amps and comparators open at different times to achieve the purpose of suppressing noise. Through theoretical analysis and simulation results show that the POP noise suppression system can control the op amp and comparator at the beginning,1. 5ms and 2ms,by the switch to open up,reduce the noise figure and obtain a good POP noise suppression results.关键词
