Abstract :
A high-swing, high-drive CMOS buffer amplifier with a good stability over a wide range of capacitive and resistive loads is presented. A new area efficient output stage with a relatively small compensation capacitor has been used. The buffer was designed as a standard cell for analog and mixed mode VLSI applications and the current implementation is in a standard 3-μm p-well CMOS process. Simulations revealed a drive capability of 140 kHz into a 5000-pF load. The buffer has rail to rail output drive for resistive loads greater than 10 kΩ. The buffer had acceptable total harmonic distribution with loads down to 270 Ω
