摘要： A discrete digital transceiver includes a receiver sample and hold module, a discrete digital receiver conversion module, a transmitter sample and hold module, a discrete digital transmitter conversion module, clock generation module, and a processing module. The receiver sample and hold module samples and holds an inbound wireless signal in accordance with a receiver S&H clock signal. The discrete digital receiver conversion module converts the receiver frequency domain sample pulse train into an inbound baseband signal. The transmitter sample and hold module samples and holds an outbound signal to produce a transmitter frequency domain sample pulse train. The discrete digital transmitter conversion module converts a transmitter frequency domain sample pulse train into the outbound wireless signal. The clock generation module generates S&H clock signals in accordance with a control signal. The processing module generates the control signal such that the S&H clock signals are shifted.

摘要： A receiver includes a sample and hold module, a discrete time filter module, and a conversion module. The sample and hold module includes a sample switching module, an impedance module, and a hold switching module. The sample switching module outputs samples of an inbound wireless signal in accordance with a sampling clock signal. The impedance module temporarily stores the samples. The hold switching module outputs a filtered representation of the samples in accordance with a hold clock signal to produce a frequency domain sample pulse train, wherein a filter response of the sample and hold module is in accordance with a ratio between the sampling clock signal and the hold clock signal. The discrete time filter module, which may be programmable, filters the frequency domain sample pulse train. The conversion module, which may be programmable, converts the filtered sample pulse into an inbound baseband signal.

摘要： A low pass filter circuit includes an amplifier having a single-ended output. A first line and a second line are arranged to receive a differential signal. A first switch selectively connects the first line to a first input of the amplifier in a first cycle of operation having a first observation window. A second switch selectively connects the second line to a second input of the amplifier in a second cycle of operation having a second observation window that is at least partially coincident with the first observation window. A signal measuring stage that is supplied with a modulated input signal generates the differential signal. The signal measuring state has an input switch to reverse a polarity of the differential signal applied to the first and second lines of the low pass filter circuit.

摘要： A configurable switched capacitor block includes a switched-capacitor (SC) sampling circuit, a fully differential amplifier, an SC feedback circuit, and a comparator. The SC sampling circuit is coupled to receive an input signal and to selectively generate a sampled signal to a differential input of the amplifier. The SC feedback circuit is coupled between the differential inputs and the differential outputs of the amplifier to selectively control a feedback of the amplifier. The comparator is coupled to the differential outputs of the amplifier to generate an output signal. The configurable switched capacitor block has multiple modes of operation which are selectable by programming the SC sampling circuit and the SC feedback circuit.
