Abstract

A current sensing circuit includes a sensing resistor, a current monitor, a variable resistor, and a processor. The sensing resistor is disposed on a to-be-sensed circuit and coupled between first and second first voltage terminals of the to-be-sensed circuit. The current monitor includes first and second terminals. A first winding is coupled between the first terminal and the first voltage terminal, and a second winding is coupled between the second terminal and the second voltage terminal. The variable resistor is connected in series with the first winding between the first voltage terminal and the first terminal. The current monitor obtains a sensed current according to a first voltage on the first terminal, a second voltage on the second terminal, and an impedance of the sensing resistor and generates a sensing signal. The processor determines whether to adjust an impedance of the variable resistor according to the sensing signal.
