A new type of charge transfer circuit is proposed.The circuit consists of a MOS transistor and a capacitor. When calculating the matching degree of the correlation, the difference between the related quantities is firstly calculated, and then the difference is amplified to improve the calculation accuracy of the circuit. Adopting the way of charge transfer circuit, the power consumption of the circuit is greatly reduced, meanwhile, the circuit also has the function of automatically correcting the threshold deviation of the MOS transistor to minimize the error caused by the manufacturing process. The test results from the standard CMOS process show that the power consumption is only 12μW at 50 Hz.
