    摘要： A sampling filter device wherein the filter characteristic is variable without using a control signal of a complicated waveform is provided. A sampling filter device 105 has integration capacitors 130 and 131, an integration time adjustment section 180, and a plurality of switches 100, 101, 110, and 111. Input current is integrated in different time duration with one clock and is stored in the integration capacitors 130 and 131 and charges stored in the integration capacitor from several clocks before to one clock before are added and the result is output. When charge is stored in the integration capacitors 130 and 131 with each clock, the integration time duration is changed, whereby it is made possible to weight and add output charge and the filter characteristic changes.

    摘要： Disclosed are a nonlinear distortion compensating receiver and nonlinear distortion compensation method, wherein nonlinear distortion is reduced with a simple circuit configuration. A correction (opposite characteristics) filter (104) has characteristics opposite that of the frequency characteristics of a direct sampling mixer (102) and corrects signals sampled by the direct sampling mixer (102). In the main path, a LPF (106) extracts a frequency band component of a desired signal from the corrected signal. In the replica path, a BPF (107) extracts the frequency band component of a blocker signal from the corrected signal. A cubing circuit (108) uses the frequency band component of the blocker signal to generate a replica signal for the nonlinear distortion. An adaptive filter (110) performs filter processing on the replica signal while updating the filter coefficients. A subtractor (111) subtracts the output signal of the adaptive filter (110) from the frequency band component of the extracted desired signal and outputs the subtraction result as the desired signal.
