Abstract: A common mode control circuit reduces abrupt voltage changes at the outputs of a pair of amplifiers which, in turn, reduces EMI and distortions that occur when the correlation between the signals fed to the four channels of an audio system diminishes. The common mode control circuit generates for each amplifier a reference potential that is a saturated replica of the respective differential input signal of the amplifier that saturates when the amplifier switches to a bridge configuration.
Abstract translation: 共模控制电路减少了一对放大器的输出端的突变电压变化，这又降低了当馈送到音频系统的四个通道的信号之间的相关性减小时发生的EMI和失真。 共模控制电路为每个放大器产生作为当放大器切换到桥接配置时饱和的放大器的相应差分输入信号的饱和副本的参考电位。
