Abstract—A configuration of operational transconductance amplifier (OTA) based on floating-gate MOSFETs for lowpower, low-voltage, and low-frequency applications is presented in this paper. The main features of the proposed OTA are design simplicity and rail to rail input voltage at supply voltage of ±0.5 V. The proposed OTA has high output impedance, good stability, and reduced power consumption of 36 μW. PSpice simulation results using 0.18 μm CMOS technology are presented to prove the results achieved, and in the light of them, the major characteristics of the circuit are manifested.
Index Terms—Floating-gate MOSFET, low voltage, low power, threshold voltage, OTA.
