Abstract
A frequency compensated current output circuit with increased gain. The current output circuit is an improved current mirror where the gate of an output transistor (MP06) is coupled to an impedance (Ra) located in the conductive path of the mirror transistor (MP05), so that the current flowing out of the circuit is increased by an amount proportional to the resistive value of the impedance (Ra). The circuit includes a frequency compensation network (Rc, Cc) to offset the gain peaking effects which occur in the frequency response of the circuit due to the gain impedance. An output amplifier is described using the current output circuit. Other embodiments are described.
