Abstract
Innovations in circuit design have resulted in a high-performance wide band operational amplifier made by standard integrated-circuit production processes. A new class-B output circuit with very low distortion and high quiescent current stability a coupling method for differential amplifier stages incorporating the elimination of amplifier stages at high frequencies to obtain a first-order frequency response and an input stage combined with a level shift with lateral p-n-p transistors having capacitive feed forward to increase the bandwidth are used in this amplifier. A unity gain bandwidth of 50 MHz with an open-loop voltage gain of 3.10/SUP 5/ and an input bias current of 10 nA are obtained.Keywords
