Abstract

A physical quantity detection device includes a switched capacitor filter circuit having a first sample-and-hold circuit adapted to sample and hold a first signal, which is based on an output signal of a physical quantity detection element, an amplifier circuit to which an output signal of the first sample-and-hold circuit is input, and a first switched capacitor circuit to which a first output signal of the amplifier circuit is input, wherein an output signal of the first switched capacitor circuit is input to the amplifier circuit, and an A/D conversion circuit adapted to perform an A/D conversion on an output signal of the switched capacitor filter circuit.
