In this work, the low-voltage current feedback operational amplifier (CFOA) with bulk-driven, quasi-floating-gate (QFG) transistor and bulk-driven-quasi-floating-gate (QFG) transistor techniques to operate under low supply voltage is proposed. The proposed circuits were design based on the voltage follower and current follower while the output stages are designed base on the voltage follower. The CFOA circuits are designed by using the 0.18 mu m CMOS technology and supply voltage operated 1 V. Simulation results shows output impedance of CFOA with bulk-driven, quasi-floating-gate (QFG) MOS transistor and bulk-driven-quasi-floating-gate (BD-QFG) MOS transistor are 55.72 Omega dB, 43.88 Omega dB, and 41.63 Omega dB, respectively. Finally, the proposed BD, QFG and BD-QFG MOS transistors techniques can used before the ultra-low voltage and low-power CFOA circuits.
