Various embodiments are directed to apparatuses and methods to generate a first signal representing modulation data and a second signal representing an amplitude of the modulation data, the first signal and the second signal to depend on an output signal and vary a power supply voltage to a gain stage in proportion to the amplitude of the modulation data.

Power management in transceivers

In various embodiments, apparatuses and methods are disclosed that may be able to implement a multi-layer, three dimensional routing between a decoupling component and an input port for a SoC or MCM. A three dimensional (3D) structure may provide a defined current return path from the decoupling component to the input port. The current return path may be constrained by design to provide an equal and opposite electromagnetic flux to the input port thereby reducing series inductance between the input port and the decoupling component.

The controller is configured to selectively couple, on a cold boot up, either the passive regulator circuit or the switching regulator circuit between an input voltage port and an output load based on the determination of parameters.

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.

Apparatus and method to process signals from one or more transmission sources

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.

Quadrature gain and phase imbalance correction

According to various embodiments, a system, an apparatus and a method are presented that relate to determining and correcting signal imbalances between output samples of an analog-to-digital (A-D) converter array (that may be implemented as part of a wideband ADC). A statistic module and correction module are associated with the A-D converter array. The statistic module is configured to receive digital samples from the plurality of A-D converters, and generate a statistical sample value for each A-D converter using a set of digital samples received therefrom. The correction module is configured to, for at least one of the plurality of A-D converters, determine an offset value by comparing the statistical sample value for the at least one of the plurality of A-D converters with a reference value, and apply the offset value to a digital sample from that at least one A-D converter to generate a corrected digital sample.
