Abstract
A current sensing circuit includes a current sensing unit, a feedback control unit and a digital output unit. The current sensing unit senses a current and produces a pulse signal according to at least one reference signal and at least one feedback signal. The current sensing unit includes a first capacitor set and a second capacitor set. The current sensing unit selects at least one capacitor in the first capacitor set and at least one capacitor in the second capacitor set according to the current value so as to adjust the precision of the current sensing circuit. The feedback control unit is coupled to the current sensing unit and produces the feedback signals 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.
