Abstract
A sensor module includes: a count unit configured to generate first to n-th count values of a time event of one of a measurement target signal output from a physical quantity sensor and a reference periodic signal output from a reference periodic signal generation unit in synchronization with the other; a time digital value generation unit configured to generate first to n-th time digital values based on a phase difference between the measurement target signal and the reference periodic signal; and a combined output value generation unit configured to generate an i-th combined output value based on the i-th time digital value and the i-th count value. A quantization error of the j-th combined output value is fed back to generation of the (j+1)-th combined output value, and a period of a change in the physical quantity when a frequency, at which the physical quantity changes, is a maximum frequency is longer than eight times an average period in which first to n-th combined output values are generated.
