摘要： A detection device includes a drive circuit of a physical quantity transducer, a synchronization signal output circuit, and a detection circuit that performs detection of a physical quantity signal based on a physical quantity. The synchronization signal output circuit includes a delay locked loop (DLL) circuit that includes: a delay control circuit that outputs a delay control signal and a delay circuit that includes a plurality of delay units in which a delay time is controlled by the delay control signal; an adjustment circuit that includes at least one delay unit in which a delay time is controlled by the delay control signal, and outputs a signal obtained by delaying an input signal based on the output signal from the drive circuit to the DLL circuit; and an output circuit that outputs the synchronization signal based on multi-phase clock signals from the DLL circuit.
