400_CPS_SERVO_AMPLIFIER_SUPPRESSES_THIRD_HARMONIC

Published:2009/7/23 23:39:00 Author:Jessie | From:SeekIC

Single-transistor operational amplifier for 400aps servosystems gives accurate 90-deg phase shift at carrier frequency and open-loop gain of 34 db. Circuit resonance at 1,200 cps keeps third harmonic 20 db down.-M. Schmidt, Operational Amplifier Suppresses Third Harmonic, Electronics, 35:13, p 74.
