1.5 V large-driving class-AB buffer amplifier with quiescent current control

A 1.5 V large-driving class-AB buffer amplifier with quiescent current control suitable for output driver application is proposed. An experimental prototype buffer demonstrated that the circuit draws only 80 (mu)A static current, and exhibited the rise time of 0.4 (mu)s and fall time of 1 (mu)s under a 100 (omega)//150 pF load.
