Abstract:
A system for a Class AB Amplifier output stage that includes a first push pull system connected to an output terminal including a first driving transistor coupled to the output terminal and a second push pull system connected to the output terminal including a second driving transistor coupled to the output terminal. The amplifier also includes a current mode amplifier where the current mode amplifier's output is coupled to the first driving transistor's gate. The amplifier further includes a pair of resistors, a first resistor coupled to a first input terminal of the current mode amplifier, a second resistor coupled to a second input terminal of the current mode amplifier and coupled to the second driving transistor.
