Integrated circuit for reducing radio frequency interference due to antenna effects

Abstract

The invention provides an integrated circuit for reducing radio frequency interference due to antenna effects. In one embodiment, the integrated circuit includes a pre-stage audio processor and a post-stage power amplifier. The pre-stage audio processor receives a left channel input signal and a right channel input signal, processes the left channel input signal to obtain a positive left channel signal and a negative left channel signal, and processes the right channel input signal to obtain a positive right channel signal and a negative right channel signal. The post-stage power amplifier amplifies the positive left channel signal and the negative left channel signal to obtain a left channel output signal, and amplifies the positive right channel signal and the negative right channel signal to obtain a right channel output signal.
