Abstract

A low-voltage linear operational transconductance amplifier (OTA) with rail-to-rail differential mode input signal capability is designed and fabricated by 0.8 /spl mu/m CMOS technology. The circuit is capable of operating at supply voltage larger than two times the MOS transistor threshold voltage V/sub T/. When the supply voltage is /spl plusmn/1 V, the total harmonic distortion (THD) is less than 1.8% for 2 V peak-to-peak (V/sub pp/) input.
