ABSTRACT:
In a semiconductor integrated circuit including plural types of transistors having different threshold voltages, a plurality of oscillators including respective types of transistors are provided. The respective oscillation frequencies of these oscillators are counted, and based on the count values, a voltage to be set on a power supply voltage device for the semiconductor integrated circuit is determined according to the count values.
