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 error signal generation unit receives the phase signal and a reference phase signal and generates a phase error signal, which is fed to the glitch correction unit. 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 |
20120013407 | METHOD AND SYSTEM FOR COMPENSATION OF FREQUENCY PULLING IN AN ALL DIGITAL PHASE LOCK LOOP - The present invention is a method and system for compensation of frequency pulling in an all digital phase lock loop. The all digital phase lock loop can utilize a multi-phase oscillator including latches with substantially all of the latches paired with a corresponding dummy cell. The dummy cells can have impedance characteristics, such as variable capacitance values which correspond to the variable capacitance value of the latches such that the sum of the two variable capacitance values remains substantially constant, even when the polarity of the reference clock signal changes. The dummy cells can be, for example, variable capacitors or dummy latches. The phase lock loop can also include a multiplying unit. The multiplying unit can receive a reference clock signal and generate a frequency multiplied reference clock signal. | 01-19-2012 |

20130271190 | VERNIER PHASE TO DIGITAL CONVERTER FOR A ROTARY TRAVELING WAVE OSCILLATOR - A phase to digital conversion circuit with improved resolution for a rotary traveling wave oscillator. The phase to digital conversion circuit connects with a closed loop transmission line via a plurality of signal lines or nodes distributed along the transmission line. As an oscillating signal propagates around the transmission line, a time waveform of the signal at each of the plurality of signal lines is transmitted to a corresponding plurality of latches. Upon a triggering condition, the plurality of latches simultaneously samples the signals from the plurality of signal lines. At least two reference clock signals are switchably coupled with the plurality of latches latch for triggering the plurality of latches based on an edge transition in each of the reference clock signals compared with an edge transition in each of the signals from the plurality of taps. | 10-17-2013 |
20150236847 | SIGNAL-GENERATING CIRCUIT AND WIRELESS COMMUNICATION DEVICE - A signal-generating circuit includes a voltage-controlled oscillator that generates an oscillated signal; a first frequency divider that generates a first divided signal by dividing the oscillated signal; a second frequency divider that generates a second divided signal by dividing the divided signal; a phase comparator that receives as input the second divided signal and a reference signal and outputs two signals corresponding to a phase difference therebetween; a loop filter that extracts a low frequency signal between the two signals to be output to the voltage-controlled oscillator; a third frequency divider that generates a third divided signal by dividing the first divided signal; a first frequency converter that generates a first frequency converted signal by multiplying the oscillated signal by the third divided signal; and a first multiplier that generates a multiplied signal by multiplying the first frequency converted signal by a first multiplication number. | 08-20-2015 |

20110058622 | METHOD AND APPARATUS FOR PROVIDING HIGH EFFICIENCY CARTESIAN MODULATION - The disclosure relates to a method and apparatus for providing efficient signal transmission. Conventional linear amplifiers are most efficient when operated in compressed mode. In the compressed mode, the digital power amplifier switches between the on and off modes. A digital power amplifier operates in compressed mode only if the incoming signal is an on-off constant envelop signal. In one embodiment, the disclosure provides a method and apparatus for converting a digital baseband signal to on-off constant envelop signals for processing through binary-weighted or thermometer-weighted amplifier which are operated in compressed mode. | 03-10-2011 |

20090275860 | Centesis Instrument - A centesis instrument, wherein a patient applies a contact part to a palm, a finger, or an arm in the state of gripping an outer tube by hand and presses the outer tube against its measured portion. A third coiled spring is compressed to increase spring power. When the outer tube reaches a prescribed position, the tip face of the vertical portion of a centesis button reaches a hole part, and a projected part is allowed to be pressed. When the patient presses a button body from a direction perpendicular to the axis of the button body by using a finger at that position, a locking piece is separated from a locking part and the centesis needle of a centesis needle unit is instantaneously projected from the opening part of the contact part to the measured portion by the spring power of the third coiled spring for centesis. Thus, a prescribed amount of blood can be taken out from the measured portion. | 11-05-2009 |
