The invention relates to a current supply control and compensating touch-control capacitance sensing method and a device thereof. The device is composed of a capacity transducer which is connected with one or more touch-control input points and a sensing capacitor; each touch-control input point is connected with a touch-control capacitor; the method is as follows: clearing electric charges among the sensing capacitors and the touch-control capacitor firstly, then generating a variable current supply to charge the touch-control capacitor, after being charged, the charges of the touch-control capacitor are transferred to be accumulated on the sensing capacitor, thus generating an accumulating voltage (Vs), and counting an enumerated value, that is, N is equal to N plus 1; repeating the steps until the accumulating voltage (Vs) reaches a voltage reference (Vref), and when the enumerated value N is in accordance with the standard, the touch control of the touch-control input point is generated.
