Low offset transconductance amplifier in an analog electronic cochlea

摘要

A low offset transconductance amplifier, in an analog electronic cochlea comprises: first and second differentially connected input transistors; an input current source transistor; an output current sink transistor; first means for inducing a current in the output current source transistor in response to the first input transistor; and second means, for inducing a current in the output current sink transistor in response to the second input transistor, including a cascode transistor.
