20120013363 | METHOD AND SYSTEM FOR A GLITCH CORRECTION IN AN ALL DIGITAL PHASE LOCK LOOP - The present invention relates to a method and system for glitch correction in an all digital phase lock loop. An all digital phase lock loop can include a phase error signal generation unit, a multi-phase oscillator, a glitch correction unit, and a phase to digital converter. The phase to digital converter receives a multi-phase signal from the multi-phase oscillator and generates a phase signal.

The glitch correction unit removes the glitches in the phase error signal by a portion of the phase error signal. The phase lock loop can also include a phase rotator and a calibration block. The calibration block instructs the phase rotator to rotate the multi-phase signal by the phase rotation which generates the minimum number of glitches. | 01-19-2012 |

The variable rate clock generator is used to provide an oversampling clock for the DAC. The rate of the oversampling clock is adjustable and is selected so that an upconverted version of a DAC image created by the DAC is steered away from frequencies within the receive frequency band. A notch-effect low-pass filter (NELPF) may also, or alternatively, be used in the transceiver to reduce transmission spurious effects in the receive frequency band. | 09-11-2008 |
20110075755 | MULTIPHASE DIRECT RF FREQUENCY TO DIGITAL CONVERTER AND RELATED METHOD - The disclosure provides an effective means for fine-resolution determination of the frequency content of an RF signal using low speed digital circuits. The disclosure relates to a method and apparatus for decomposing a high frequency RF signal into several low frequency signals or data streams without loss of any information and without the use of extraneous circuit components such as local oscillators, mixers or offset phase-locked loops. Single or multiple phase oscillator outputs are fed directly to a single or multiple direct RF frequency-to-digital (DrfDC) circuits. The front end of the DrfDC circuit decomposes a high frequency signal into several low frequency signals without loss of any information. The low frequency signals are processed by the back-end of the DrfDC and converted into digital data streams. The digital data streams are then combined and averaged to represent the frequency of the input RF signal. | 03-31-2011 |
