Abstract
Compensating for fluctuations in the gain characteristic of the gain slope in the event of changes in ambient temperature without increasing circuit scale or adding to costs. A thermistor, which is a thermally sensitive resistance element in which resistance changes with a negative temperature characteristic according to the ambient temperature, is employed as the gate resistance of an FET, and the circuit functions such that fluctuations in the gain characteristic of the gain slope with respect to ambient temperature are canceled out by fluctuations in the value of Q with respect to the ambient temperature, thereby compensating for fluctuations in the gain slope characteristic in the event of changes in the ambient temperature.
