Abstract: A system includes a pipeline analog-to-digital converter as a first stage to process an input signal, and a successive approximation register (SAR) analog-to-digital converter as a second stage to process the input signal. The SAR analog-to-digital converter includes a power adjustment element to adjust a reference voltage of the SAR analog-to-digital converter to match a full scale voltage of the pipeline-analog-to-digital converter.

Abstract: A method and apparatus is disclosed to determine communications receiver parameters from multiple channels of a received communications signal and to configure and/or adjust communications receiver parameters to acquire one or more channels from among the multiple channels of the received communications signal. A communications receiver observes a multi-channel communication signal as it passes through a communication channel. The communications receiver determines one or more communications receiver parameters from the multiple channels of the received communications signal. The communications receiver configures and/or adjusts communications receiver parameters to acquire the one or more channels from among the multiple channels of the received communications signal.

Abstract: Embodiments provide transmitter topologies that improve the power efficiency and bandwidth of RF transmitters for high transmission power applications. In an embodiment, the common-emitter/source PA of conventional topologies is replaced with a current-input common-base/gate PA, which is stacked on top on an open-collector/drain current-output transmitter. The common-base/gate PA protects the output of the transmitter from large output voltage swings. The low input impedance of the common-base/gate PA makes the PA less susceptible to frequency roll-off, even in the presence of large parasitic capacitance produced by the transmitter. At the same time, the low input impedance of the common-base/gate PA reduces the voltage swing at the transmitter output and prevents the transmitter output from being compressed or modulated. In an embodiment, the DC output current of the transmitter is reused to bias the PA, which results in power savings compared to conventional transmitter topologies.
