Abstract
A class-D amplifier includes a loop filter, a PWM generator coupled to the loop filter, a first multiplexer coupled to the PWM generator, a second multiplexer coupled to the PWM generator, and a power stage coupled to the first multiplexer and the second multiplexer. The loop filter is used to generate positive and negative LPF signals according to first and second analog signals, and first and a second feedback signals. The PWM generator is used to generate positive and negative PWM signals according to the positive and negative LPF signals respectively. The first and second multiplexer are used to output first and second MUX signals selected from a signal group. The power stage is used to generate a positive output signal to a positive output terminal according to the first MUX signal, and a negative output signal to a negative output terminal according to the second MUX signal.
