Abstract
The JFET transistor differential amplifier herein serves as an input stage, as for an electrometer operational amplifier, and exhibits high input impedance and low leakage current. This is achieved by biasing the JFET transistors so as to operate in the ohmic region rather than the saturation region of their characteristic drain current-gate to source voltage curve.
