ABSTRACT:
A method of forming a differential amplifier on a substrate which has a greater tolerance for applied voltages and a chip so formed. The differential amplifier circuit on a substrate has additional transistors connected with resistors which form a voltage divider, thereby sharing the voltage stress which may be applied and accommodating enhanced capabilities for the differential amplifier.
