    摘要: A low-pass filtering circuit and method are disclosed. The circuit includes a low-pass filter with a capacitor, and a multiplier configured to multiply the capacitance of the capacitor by feeding-back a high-frequency signal apparent in an output signal of the low-pass filter to the capacitor.
