TEMPERATURE_COMPENSATED_ANTILOG_CONVERTER

Published:2009/7/13 22:44:00 Author:May | From:SeekIC

Circuit provides antilog conversion with high degree of temperature compensation. Article gives design equations and application instructions. Circuit is for positive inputs; for negative inputs, use PNP transistors such as 2N4058 in place of those shown. Adjust value of R4 to make output of opamp A2 exactly 10 times input voltage ei when input is -1 V.-G. B. Clayton, Experiments with Operational Amplifiers, Wireless World, Jan, 1973, p 33-35.
