Abstract
A rail-to-rail amplifier that maintains a high common-mode rejection ratio (CMRR) over the whole common-mode range and has a low harmonic distortion despite the use of relatively small output devices is discussed. The circuit, which measures only 0.3 mm2 in a 3-μm technology, has a quiescent current consumption of 600 μA and a CMRR larger than 55 dB. It handles up to 4 nF, and can, with a 5-V supply, drive 3.8 Vpp into 100 Ω (0.1% total harmonic distortion at 10 kHz)
