Abstract
A differential amplifier (10) includes three unilateral field effect transistors (12, 14, 16) formed in a common well (40) of a semiconductor material. Each of the three unilateral field effect transistors (12, 14, 16) has an asymmetric channel doping profile. The performance of the differential amplifier (10) is significantly improved by properly orienting the three unilateral field effect transistors (12, 14, 16).
