Abstract

A filter includes a filter circuit, a first processing circuit, and a second processing circuit. The filter circuit receives an input signal from an input node of the filter, and converts the input signal into a voltage output. The first processing circuit provides a first control voltage to an output node of the filter according to the voltage output, wherein the first control voltage is derived from an alternating current (AC) component of the voltage output. The second processing circuit provides a second control voltage to the output node of the filter according to the voltage output, wherein the second control voltage is derived from applying DC level shift to a direct current (DC) component of the voltage output.
