Abstract
A delay circuit is used for receiving an input signal from a signal source. The delay circuit includes a delay unit, a switch unit, and a generator. The switch unit is used for receiving a voltage from a power supply and selectively transmitting the voltage to the delay unit according to the input signal. The generator is coupled to the power supply for generating an output signal. The output signal is equivalent to the input signal that is delayed for a predetermined time period. Wherein the delay unit is used for generating an electrical signal according to the voltage and transmitting the electrical signal to the generator. The delay unit includes an adjustable capacitor coupled between ground and an interconnection of the switch unit and the generator. An electronic device including the delay circuit is also provided.
