摘要： Provided are a direct sampling circuit and a receiver using a discrete time analog process and having a filter effect of a steep attenuation characteristic in a narrow-pass band without lowering a sampling rate. In a discrete time direct sampling circuit (13), the positive phase side and the inverse phase side are both sampled by a local signal for a differential current output of a differential voltage/current conversion unit (1011) and electric charge is accumulated in a charge sampling capacitor. The latest accumulated charge at the positive phase side and charge accumulated at the inverse phase side before a predetermined number of samples are combined with the charge accumulated in a history capacitor (1043) in the past. Thus, it is possible to realize equivalently high-degree FIR filter characteristic.

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.
