Abstract

In this paper, a novel CMOS voltage follower with resistive-load drivability is proposed. The proposed follower consists of only three MOS transistors and one current mirror. The output voltage of the circuit is insensitive to MOS transistor device parameters including the threshold voltage. Simulations of the voltage follower demonstrate that a THD of 0.5% is obtained with a 1 V_p-p, 10-kHz sinewave input and a 10-kΩ load resistance. Similar results were obtained using CMOS 4007 IC's.
