摘要
Various embodiments include a system and method that control idling current of a pulse modulated driver. The system may include an audio input device configured to receive an audio input signal. The system can include sliding bias control circuitry configured to generate a sliding bias control signal based on a level of the audio input signal. The system may include sliding bias generation circuitry configured to generate a sliding bias voltage superimposed onto the audio input signal to generate a pulse modulated driver input signal that is input into an amplifier. The sliding bias voltage may be based on the sliding bias control signal.
