Abstract
The light detection efficiency of Photon detecting components is very much dependent on the operating temperature. Rise in operating temperature reduces their ability of photon detection and reduced output signal. This effect becomes prominent in the cases where very weak signals are needed to be detected. There are various methods which can be applied to cater for the situation of changing ambient temperature or the temperature of the component itself. This study present a method which tracks the temperature changes as seen by the device and hence adjusts the bias voltage being supplied to it. The bias voltage mainly depends upon the temperature coefficient of the component and hence adjusts itself. Design and testing method of bias power supply are presented along with the graphical presentation of result.
