Abstract: In this paper a bulk driven Fully cascoded operational transconductance amplifier(FCOTA) is designed. OTA applications are designed for voltage controlled current amplifier, filters and analog subtractor. With the current sizing method, all transistors in FCOTA work under weak inversion field. The total current in the proposed amplifier in terms of nano amperes only. As part of low power the circuit operated with the power supply of 0.8V. The main important features of the design are good linearity and accuracy. Full input and output voltage swings. This circuit has been constructed using CMOS technology with UMC90 nm. The circuit’s total power consumption is 620nW.
