Abstract
A detection circuit includes a synchronous detection circuit (synchronous detection section) that synchronously detects a signal that includes a detection signal of a vibrator (an output signal of an amplifier), a switched capacitor filter (SCF) circuit that filters a signal that has been synchronously detected by the synchronous detection circuit (an output signal of a programmable gain amplifier), and an output buffer that buffers and outputs a signal that has been filtered by the SCF circuit, the gain of the SCF circuit being larger than 1.
