Abstract :
A CMOS op amp (operational amplifier) is reported which has a rail-to-rail voltage range at its input as well as its output. An area-efficient output stage has been used. While the entire op amp occupies only 600 mil2, when used as a unity-gain buffer and with ±5-V supplies, the op amp can drive a 9-Vpp/1-kHz sine wave across a 300-Ω load with -64 dB of harmonic distortion
