Abstract
A current sensing circuit including a current sensing unit, a feedback control unit, and a digital output unit is provided. The current sensing unit senses a current and generates a pulse signal according to at least one reference signal and at least one feedback signal. The feedback control unit is coupled to the current sensing unit and generates the at least one feedback signal according to a clock signal and the pulse signal. The digital output unit is coupled to the current sensing unit and outputs a digital signal according to the pulse signal. The digital output unit counts an amount of pulses of the pulse signal in a predetermined time period to output the digital signal, wherein the amount of pulses is positively correlated with a value of the current.
