Embodiment Construction
[0016] Please refer to FIG. 2 . FIG. 2 is a schematic diagram of the device error correction system 10 of the present invention applied to an RC filter circuit 70 . The component error correction system 10 includes a current generator 20 , which can generate two currents, which are respectively output to a reference voltage generator 30 and a voltage divider circuit 40 . The divided voltage of the voltage divider circuit 40 and the reference voltage generated by the reference voltage generator 30 are respectively input into two input terminals of a comparator circuit 50, and the comparison result is then input into a correction circuit 60 to control the correction circuit 60 to correct the filter circuit. 70 to make the necessary corrections. In this embodiment, the correction circuit 60 is equivalent to a variable capacitor, which is electrically connected to the filter circuit 70 in parallel. The comparison circuit 50 is used as an analog / digital conversion circuit for conv...
