A High Speed JFET Operational Amplifier Based on Complementary Bipolar Process

Published: 31 December 2021 Publication History

Abstract

In this paper, we present a high speed junction field-effect-transistor (JFET) operational amplifier (OPA). It adopts N-channel JFET (N-JFET) differential input stage, full complementary differential gain stage and common-emitter output stage. It is fabricated on an especial complementary bipolar process compatible with N-JFET module. Unlike the conventional P-channel JFET (P-JFET) OPAs, it not only achieves very low input bias current & offset current (< 10 pA), very low input offset voltage (< 10 μV) and low input voltage noise spectral density (< 10 nV/√Hz), but also offers much higher output voltage slew rate (> 40 V/μs), much wider -3dB bandwidth (> 30 MHz) and rail-to-rail output. Combined with high input impedance, great precision, low noise and high speed, it is an ideal amplifier for driving ADC input, buffering DAC output, photodiode amplification and fast active filter, etc.
