Abstract:
A device of measuring a duty cycle includes a resistor-capacitor circuit and a control circuit. The resistor-capacitor circuit is used to generate a first voltage when a reference signal is in a first state, and generate a second voltage and a third voltage when the reference signal is in a second state. The control circuit is coupled to the resistor-capacitor circuit, and configured to acquire an ON-time according to the first voltage, the second voltage and the third voltage. The ON-time is a time interval during which the reference signal is in the first state.
