0.5-V bulk-driven quasi-floating gate transconductance amplifier

Abstract

This paper describes a new low-voltage low-power transconductance amplifier for low-voltage low-power signal processing applications. The proposed circuit uses bulk-driven quasi-floating gate technique to offer a 0.5 V operating power supply and high operating frequency. The performances of the proposed circuit can be conformed using PSPICE simulations. The simulation result shows that the proposed circuit provides 16.7 pW power consumption and 10 MHz open loop gain. The proposed circuit has been used to realize Tow-Thomas biquad.
