  • Circuit and method for reducing noise in class D amplifiers
    Patent number: 8416017
    Abstract: A circuit for reducing noise in Class D amplifiers has a power stage voltage control means (17, 21, 22) responsive to defined signal conditions of the audio signal input (1). The power stage voltage control means is operative to lower the voltage at the supply voltage input (31) of the amplifier's switching power output stage (30) upon the detection of a defined condition in the audio signal input such that the Class-D amplifier operates at reduced voltage (“idles”) during the defined audio input signal condition.
    Type: Grant
