Abstract:
A current analog audio amplifier having an operational amplifier current-reading and voltage-controlling current source, a voltage gain stage, an output buffer stage, a negative feedback circuit, a high-frequency compensation circuit, and a bias circuit. The operational amplifier current-reading and voltage-controlling current source is connected to the voltage gain stage. The voltage gain stage is connected to the output buffer stage. The negative feedback circuit is connected to the operational amplifier current-reading and voltage-controlling current source. The high-frequency compensation circuit and the bias circuit are connected separately to the operational amplifier current-reading and voltage-controlling current source.
