Abstract:
An amplifier having an output stage with a complementary pair of first and second transistors each coupled to an output node of the amplifier; control circuitry arranged to provide a control signal at a control node of the first transistor based on the voltage at an input node of the amplifier; and adjustment circuitry arranged to adjust the control signal to maintain the current through the first transistor above a minimum value.
