Abstract
A circuit device includes a clock signal generation circuit that generates a clock signal through an oscillation circuit, and a detection circuit including a circuit operating through an operation signal based on the clock signal. The clock signal generation circuit includes a first frequency adjustment unit which is capable of adjusting an oscillation frequency before an physical quantity transducer and the circuit device are connected to each other, and a second frequency adjustment unit which is capable of adjusting the oscillation frequency in a state where the physical quantity transducer and the circuit device are connected to each other.
