Abstract

A correction arithmetic circuit disclosed herein includes an offset temperature characteristic correction unit that corrects an offset temperature characteristic of an input signal according to an input signal characteristic at a specific temperature and a temperature characteristic at a specific input signal. A signal processor disclosed herein includes a pulse count number setting circuit that generates a pulse count number setting signal in accordance with an input signal and a pulse generation unit that generates a pulse signal by counting a pulse number of a reference clock signal according to the pulse count number setting signal. The pulse count number setting circuit corrects the pulse count number setting signal so as to cancel a frequency temperature characteristic of the pulse signal.
