A voltage buffer so-called the bulk-driven flipped voltage follower is presented. This proposal is based on the flipped voltage follower (FVF) technique, but a bulk-driven MOSFET with the replica-biased scheme is utilized for the input device to eliminate the DC level shift. The proposed buffer has been designed and simulated with a 0.35 mum CMOS technology. The input current and capacitance of our proposal are 1.5 pA and 9.3 fF respectively, and with 0.8 V peak-to-peak 500 kHz input, the total harmonic distortion is 0.5% for a 10 pF load. This circuit can operate from a single 1.2 V power supply and consumes only 2.5 muA.
