Low Voltage High Performance Floating Gate and Quasi Floating Gate CDTA

Abstract

A low voltage and low power current differencing transconductance amplifier (CDTA) based on Floating gate MOSFET (FGMOS) and Quasi-floating gate MOSFET (QFGMOS) is presented. The use of QFGMOS eliminates confined in the floating gate, degraded gain-bandwidth product, silicon area etc. The proposed circuits have been simulated using spice simulation software 180nm technology of analog devices LtSpice XVII and supply voltage used for this is ±1V.
