METHOD FOR CONTROLLING CURRENT AMOUNT FLOWING INTO CIRCUIT MODULE AND ASSOCIATED CHIP

The present invention provides a chip comprising a circuit module, a power switch and a detection and control circuit. The power switch is coupled between a supply voltage and the circuit module, and is used to selectively connect the supply voltage to the circuit module, and control a current amount flowing into the circuit module according to at least a control signal. The detection and control circuit is coupled to the power switch, and is used to detect a first signal generated by a first circuit positioned surrounding the circuit module, and compare the first signal with a second signal in a real-time manner to generate the control signal to adjust the current amount flowing into the circuit module.
