A proximity sensor that detects the distance between two coils is disclosed. In one example, the proximity sensor includes a reference signal generation circuit, a first coil, a second coil, a clock signal generation circuit, and a switched capacitor circuit. The reference signal generation circuit applies a first alternating voltage to the first coil and transmits a reference signal synchronized with the first alternating voltage to the clock signal generation circuit.
