Abstract
A class AB low voltage output stage with improved current drive capability where the signal input to the stage modulates the base drive currents of both an output transistor sourcing current to a load and an output transistor sinking current from the load. Coupling the base drive currents by means of the input amplifier permits higher drive currents to be obtained for the output transistors without increasing the quiescent current of the circuit.
