Transconductance-Parameter-Independent Low Voltage rail-to-rail OTA

Abstract

In this paper, low power-supply voltage rail-to-rail OTA which is independent of transconductance parameter is proposed. The proposed OTA is realized by utilizing characteristic of trode region MOSFET and voltage generating circuit which is inversely proportional to transconductance parameter K of MOSFET. HSPICE simulation is performed to verify the validity of the proposed circuit.
