Abstract
There is provided a semiconductor device including an oscillation circuit that includes a plurality of capacitors provided on a semiconductor substrate, a conversion circuit that converts an analog signal into a digital signal, and a switch circuit that switches the capacitors on the basis of the digital signal. Further, an oscillation frequency linearly varies with respect to a variation in the analog signal.
