20120252382 | PREDISTORTION CALIBRATION AND BUILT IN SELF TESTING OF A RADIO FREQUENCY POWER AMPLIFIER USING SUBHARMONIC MIXING - A novel and useful apparatus for and method of predistortion calibration and built-in self testing (BIST) of a nonlinear digitally-controlled radio frequency (RF) power amplifier (DPA) using subharmonic mixing. The RF power amplifier output is temporarily coupled into the frequency reference (FREF) input and the phase error samples generated in the phase locked loop (PLL) are then observed and analyzed. The digital predistortion and BIST mechanisms process the phase error samples to calibrate and test the DPA in the transmitter of the Digital RF Processor (DRP). The invention enables the characterization of nonlinearities, the configuration of internal predistortion, as well as the testing of the transmitter's analog/RF circuitry, thereby eliminating commonly employed RF performance testing using high-cost test equipment and associated extended test times. | 10-04-2012 |

20160099720 | Wideband Digitally Controlled Injection-Locked Oscillator - A novel and useful digitally controlled injection-locked RF oscillator with an auxiliary loop. The oscillator is injection locked to a time delayed version of its own resonating voltage (or its second harmonic) and its frequency is modulated by manipulating the phase and amplitude of injected current. The oscillator achieves a narrow modulation tuning range and fine step size of an LC tank based digitally controlled oscillator (DCO). The DCO first gets tuned to its center frequency by means of a conventional switched capacitor array. Frequency modulation is then achieved via a novel method of digitally controlling the phase and amplitude of injected current into the LC tank generated from its own resonating voltage. A very linear deviation from the center frequency is achieved with a much lower gain resulting in a very fine resolution DCO step size and high linearity without needing to resort to oversampled noise shaped dithering. | 04-07-2016 |

20100283665 | Mitigation of RF Oscillator Pulling through Adjustable Phase Shifting - A digitally controlled mechanism for the minimization of the self-interference caused by an amplitude modulated signal generated within a polar transmitter to the oscillator circuit, where the carrier of that transmitter is created.
