Analysis and design of an analog control loop for digital input class D amplifiers


Analog input Class D Amplifiers are widely used in battery powered systems such as mobile phones to achieve high efficiency but it suffers from a complex DAC to convert the digital audio signal into an analog one. To increase the playback time, this paper presents digital input class D amplifiers using digital modulation. The proposed Class D amplifier is… (More)
