Abstract
In the conventional temperature compensation circuit, the thermal resistor is used to perform the temperature compensation, but the provided compensation range is limited due to the temperature coefficient of the thermal resistor. The embodiment of the invention provides a temperature coefficient modulating circuit capable of amplifying the temperature coefficient of the thermal resistor, so as to provide a wider compensation range in different applications.
