Abstract: Examples of a digital transceiver, a switched-capacitor sampling mixer, and an N-stage switched-capacitor amplifier are generally described herein. The digital transceiver may include a plurality of switched-capacitor sampling mixers and a plurality of N-stage switched-capacitor amplifiers. Each mixer samples a received differential RF signal. The pair of N-stage switched-capacitor amplifiers operates as charge redistribution amplifiers. Each N-stage switched-capacitor amplifier provides a near-constant capacitive load for one of the mixers.

Abstract: A receiver and a method to process signals from one or more transmission sources. The receives includes a front-end having: an input coupling path to route an analog input signal received from one or more transmission sources; an equalizer to generate an equalized signal from the analog input signal; and an ADC to generate a digitized signal from the equalized signal. The method includes routing the analog input signal through an input coupling path; equalizing the analog input signal to generate an equalized signal therefrom; and digitizing the equalized signal to generate a digitized signal therefrom.

Abstract: Generally speaking, methods and apparatuses which correct errors related to phase and gain imbalances in quadrature tuners are disclosed. The quadrature tuner may be online and operating, receiving data. An embodiment may generate a squared signal from the IF frequency signal of the tuner. In generating the squared signal, the embodiment may enable the extraction of phase error and gain error information of the IF signal. The embodiment may determine a phase error component, a gain error component, or both, by frequency translation. The frequency translation may involve down-converting the signal associated with the error component to direct current (DC) signals and enable the determination of the associated phase error and/or gain error. The embodiments may generate an adjusted signal via the IF signal by applying a phase correction signal or gain correction signal to components used to correct the IF signal.

Abstract: Methods and systems to compensate IQ imbalances in a tuner system, including relatively wideband ZIF tuner systems and tuner systems having substantially linear frequency dependent phase imbalance, where a one-tap compensation element may be utilized to compensate frequency dependent phase imbalance. A two tone probe may be applied in controlled loop-back modes, and resultant baseband components may be used to determine a straight line from which to determine compensation.

Compensation parameters may be determined as fixed or non-adaptive compensation parameters in a digital domain and may be applied at baseband. One or more compensation values may be determined in a fixed point circuit.

Abstract: Apparatuses, systems, and methods that align channel filters for dual tuners are disclosed. An embodiment may comprise an IC having two tuners. Each tuner may have a low-noise amplifier, a mixer with a local oscillator, and channel filter. To perform a channel filter alignment, a bandwidth controller may cross-couple the local oscillator of each tuner to the input of the mixer of the opposite tuner. The bandwidth controller may adjust the frequencies of the local oscillators to produce different configuration tone frequencies at the outputs of the mixers, which are inputs to the channel filters. The bandwidth controller may then determine an amplitude difference between two separate measurements of a channel filter output and, based on a comparison of the measurements with predicted values, increment or decrement the filter bandwidth for each tuner and store parameters for the channel filters which create the largest signal amplitudes.
