Amplifier with reduced on/off transient and multi-point offset compensation |
摘要 |
Disclosed is an amplifier designed to substantially reduce an ON/OFF transient. The amplifier comprises a drive block that includes a pre-driver and an output stage. The amplifier also comprises a bypass circuit that is coupled to an output of the pre-driver. The bypass circuit of the amplifier is selectively activated to reduce the ON/OFF transient. The bypass circuit may comprise an auxiliary output stage that can be coupled to provide selective activation. The amplifier may also be configured to provide multi-point offset compensation. Also disclosed is a related method. The amplifier and the related method may be incorporated into an audio amplifier used in a cellular telephone or other mobile audio device. |
