Abstract: A technique to adjust gain and DC level of current DAC signals with offset to generate a voltage signal that is used to control power level of a power amplifier. One or more current mirrors from a set of current mirrors is programmably selected to set gain of a current-to-voltage conversion stage. A second set of current mirrors used to adjust DC level current is oppositely tracked to the current mirrors used for the gain. The opposite tracking allows for deactivation (or activation) of respective current mirrors in the second set in response to activation (or deactivation) of respective gain setting current mirrors to maintain a substantially constant DC level when gain values are changed. An additional set of current mirrors allows for independent compensation of DC offsets.

Abstract: Multiple channel synchronized clock generation scheme. A novel approach is presented herein in which synchronized clock signals are generated that can be used in parallel processing of deserialized signals. When a serial input signal is received, it can be deserialized into a plurality of parallel signals, and each of these parallel signals can be processed at a frequency that is lower than the frequency of the serial signal. Overall, the frequency at which all of the parallel signals are processed can be the same or substantially close to the frequency of the serial signal, so that throughput within a communication system is not compromised or undesirably reduced. This novel approach is operable to perform independent adjustment of the operational parameters within an apparatus that is operable to perform multiple channel synchronized clock generation (e.g., phase rotation and/or division of signals within each of the individual channels can be adjusted independently).
