Abstract :
A CMOS high dynamic range, high-drive buffer suitable for driving large capacitive loads is presented. A new area-efficient output stage has been used so that simulations reveal a drive capability of 200 kHz into a 5000-pF load. The circuit occupies only 110 mils2 in a 3-μm technology. The output range is rail to rail for R>10 kΩ. The buffer is capable of driving resistive loads down to 300 Ω with acceptable total harmonic distortion (THD)
