发明名称 Detector, physical quantity measuring device, and electronic apparatus
摘要 A detector that detects a detection signal corresponding to a driving vibration, which excites a vibrator in an oscillation loop, and a physical quantity to be measured, includes: an amplifying circuit that amplifies a signal corresponding to the driving vibration and the physical quantity; a synchronous detection circuit that detects the amplified signal of the amplifying circuit in synchronization with an oscillation signal in the oscillation loop; an impedance conversion circuit that converts an output impedance of the synchronous detection circuit; a first low pass filter to which an output signal of the impedance conversion circuit is supplied and which outputs a first detection signal; and a second low pass filter to which the output signal of the impedance conversion circuit is supplied and which outputs a second detection signal.
