摘要： A sampling mixer includes TAs (transconductance amplifiers), an in-phase mixer section connected to the TA and the TA, an opposite-phase mixer section connected in parallel with the in-phase mixer section, and a signal generator for generating a control signal for the in-phase mixer section and the opposite-phase mixer section respectively. The IIR filter using signals that underwent a current conversion by using the different transconductances is constructed, so that the filter characteristic can be designed by a weighting of the transconductance in addition to a capacitance ratio. As a result, the wide-band filter characteristic and the band-pass filter characteristic can be obtained, and deterioration of the receiving sensitivity can be suppressed by designing the filter characteristic suitable for the radio communication system.

摘要： A sampling filter of such circuitry as not requiring a high frequency REF signal even if the number of decimation is decreased. In the sampling filter, the rotate capacitor in each switched capacitor circuit including Cr (7a-7d) arranged in four parallel arrays operates in four phases of integration, discharge, reset and feedback different from each other at the same timing. Consequently, a control signal for driving the switched capacitor circuit is used commonly. As a result, the circuit scale of a DCU (104) is reduced and the frequency of the REF signal can be lowered to the frequency of an LO signal even in operation without decimation.

摘要： The present invention has an object to provide a sampling filter apparatus and a wireless communication apparatus, which are capable of changing a filter characteristic without employing complex waveforms as control signals, and also, capable of performing filtering process operations without performing a decimation, while utilizing a wide frequency space. A sampling filter apparatus 100 includes a controller 140, a plurality of integrators 150 to 154, a plurality of switches 130, 160 to 164, 170 to 174, 180 to 184, and a plurality of voltage/current converters 120 to 123. An inputted current is stored in four pieces of integrators selected among the plurality of integrators 150 to 154 by one clock, and electric charges which have been stored from four preceding clocks up to one preceding clock are added to each other so as to output the added electric charges from the remaining one integrator. When electric charges are stored in the integrators 150 to 154 in each clock, since the inputted current is switched, the electric charges to be outputted can be weighted, and thus, a filter characteristic is changed.

摘要： A receiving apparatus includes an amplification section that amplifies a received signal and a frequency conversion section that converts a frequency of the received signal, from a radio frequency to a baseband, the baseband having a lower frequency than the radio frequency. A gain control section amplifies, by a predetermined gain, the signal that has been subjected to the frequency conversion to the baseband. A voltage calibration section performs calibration on an offset voltage generated in the signal subjected to frequency conversion to the baseband. A time constant control section sets a first time constant during a reception operation and sets a second time constant, which is reduced with respect to the first time constant, during the calibration. A filter section passes a received signal of a predetermined band, with the first time constant or the second time constant, an operation control section stops operation of the amplification section during the calibration, controls the amplification section to operate during the reception operation, and controls the operation of the amplification section so as to reduce a residual offset voltage caused by switching the operation of the amplification section.
