NEUTRALIZATION_OVER_±75V_RANGE

Published:2009/7/20 21:27:00 Author:Jessie | From:SeekIC

Switching transients are attenuated in sample-and-hold circuit using DG181 FET analog switch by adding neutralization derived from complementary signal coupled through upper switch of DG181. Charge transferred from second switch is then opposed to that from main channel. Circuit is controlled by input logic signal. With compensation, change in transferred charge is less than 5 picocoulombs for input signal range from -7.5 V to +7.5 V.- Analog Switches and Their Applications, Siliconix, Santa Clara, CA, 1976, p 7-61.
