Abstract

PURPOSE:To increase the reliability of signal transmission with excellent temperature stability, by compesating the variation of current transfer rate and frequency response due to the temperature in the photo coupling element through the provision of a thermistor and a capacitor with the emitter of a transistor for amplifying purpose.
