Isolating circuit with gain compensation

Published:2011/4/8 2:49:00 Author:Nicole | Keyword: isolating, gain compensation | From:SeekIC

The total harmonics distortion of this circuit is lower than 1%, and it can automatic regulation the gain variations which is produced by temperature or other DC in photoelectric isolator. After sampling, the output singal is fed back to FET, to keep constant AC gain.
