Clock signal generation circuit, detection device, sensor, electronic apparatus, and moving object

A detection device comprising:

• a clock signal generation circuit adapted to generate a clock signal using a CR oscillator circuit;
• a drive circuit adapted to receive a feedback signal from a physical quantity transducer and drive the physical quantity transducer;
• a detection circuit adapted to receive a detection signal from the physical quantity transducer to detect a desired signal;
• and
• a control section adapted to receive the clock signal from the clock signal generation circuit, and control the drive circuit and the detection circuit,
• wherein the CR oscillator circuit operates being supplied with a power supply voltage having a negative temperature characteristic,
• the clock signal generation circuit is set to an operation enable state by releasing a power-on reset state, and supplies the control section with the clock signal, and
• the control section having started an operation due to the supply of the clock signal starts up the drive circuit and the detection circuit.
