摘要
A physical quantity detection circuit includes: an analog/digital conversion circuit performing analog/digital conversion processing on an analog signal based on an output signal from a physical quantity detection element and outputting a first digital signal; a digital arithmetic circuit having the first digital signal inputted thereto, performing arithmetic processing on the first digital signal, and outputting a second digital signal; and a regulator circuit supplying a power-supply voltage to the analog/digital conversion circuit and the digital arithmetic circuit. The digital arithmetic circuit does not perform an arithmetic processing start operation to start the arithmetic processing and an arithmetic processing end operation to end the arithmetic processing, during an analog/digital conversion period when the analog/digital conversion is performed.
