A CMOS buffer amplifier which achieves significant improvements in linearity and drive capability over previously reported high-swing amplifiers is described. The buffer operates from a 5-V supply, is capable of rail-to-rail operation at both the input and output, an exhibits a remarkably high linearity of 0.05% THD while driving 3 V/SUB p-p/ into 100 /spl Omega/ at 20 kHz.
