Abstract: A method and apparatus are disclosed for a configurable mixer capable of operating in a linear, a legacy, and a low-power mode. In the linear mode, the configurable mixer is configured to operate as a double-balanced mixer to multiply a first differential signal by a second differential signal. In the legacy mode, the configurable mixer is configured to as a double-balanced mixer to multiply a differential signal by a single-ended signal. In the low-power mode, the configurable mixer is configured to operate as a single-balanced mixer to multiply a differential signal by a single-ended signal. The operating mode of the configurable mixer may be based, at least in part, on a mode control signal. In some embodiments, the configurable mixer may be included in an analog front end of a wireless communication device.

Abstract: Aspects of a wireless apparatus and a method for handling a modulated signal include a frequency generator that produces a clock signal, a first synchronization circuit that generates a first sync enable signal based on an even edge of the clock signal, a second synchronization circuit that generates a second sync enable signal based on an even edge of the clock signal, a first divider having a first initial operating condition that generates a first IQ path based on the first sync enable signal, and a second divider having a second initial operating condition that generates a second IQ path based on the second sync enable signal, wherein the first and second operating conditions are not equal when initially powered.

Abstract: A differential RF non-linear power amplifier employing low-voltage transistors in a cascode configuration uses self-biasing solutions rather than external biasing techniques to overcome transistor breakdown problems. The self-biasing solution ensures that the cascode devices and driver device operate below breakdown voltage limitations. A low resistance circuit is placed in parallel with the self-biased circuitry to mitigate increased on-resistance created by the self-biasing solution. PMOS and NMOS inverter legs provide digital programming of the conduction angle for the power amplifier. Changing the PMOS and NMOS strengths in the chain of inverter legs changes the conduction angle.
