Abstract
The operational transconductance amplifier comprises a MOS field-effective transistor that controls the mutual conductance. The central voltage measurement circuit and the voltage addition circuit shift a gate voltage of the MOS field-effective transistor by an amount equal to the deviation of a source voltage of the MOS field-effective transistor caused by an input offset voltage Voff.
