摘要： A phase locked loop circuit (30, 100, 110) includes a controllable oscillator (42) for generating an output signal of desired frequency responsive to a control signal, a first phase detection circuit (32, 102, 112) for generating an output indicative of phase differential responsive to the output signal and a first edge of a reference signal and a second phase detection circuit (34, 104, 114) for generating an output indicative of phase differential responsive to the output signal and a second edge of a reference signal. The control signal to the controllable oscillator (42) is driven by the outputs of the first and second phase detections circuits.

摘要： A system and method for low-cost performance and compliance testing of local oscillators and transmitters for wireless RF applications. A preferred embodiment comprises observing a digital signal from within an RF circuit, manipulating the signal with digital signal processing techniques, and determining if the RF circuit passes a test based upon results from the manipulating. Since the signal is clocked at a much lower frequency than an RF output of the RF circuit and the manipulation is performed digitally, testing can be performed at different stages of the production cycle and expensive test equipment can be eliminated.

摘要： A fully digitally-controlled LC tank oscillator (DCO) uses a bank of more significant binary-weighted and/or less significant equally-weighted capacitors that are switched between only two voltage potentials. The time-averaged value of capacitance of predetermined less significant capacitors is determined by dithering between the two states to achieve a further refinement in the resolution of the resonating frequency.

摘要： A technique of time dithering a fully digitally-controlled oscillator (DCO) tuning input employs a shift register 1306 and a multiplexer 1308 responsive to a sigma-delta modulated delay control to minimize spurious tones generated by a DCO 200. The shift register 1306 is clocked via a divided-down high-frequency reference provided by the DCO 200 output signal. The multiplexer 1308 is clocked via a frequency reference that is reclocked and synchronized to the DCO 200 output signal. The multiplexer 1308 output is thus time dithered in response to a delay control to minimize perturbations caused by switching.

摘要： An all-digital frequency synthesizer architecture is built around a digitally controlled oscillator (DCO) that is tuned in response to a digital tuning word (OTW). In exemplary embodiments: (1) a gain characteristic (KDCO) of the digitally controlled oscillator can be determined by observing a digital control word before and after a known change (Δfmax) in the oscillating frequency; and (2) a portion (TUNE_TF) of the tuning word can be dithered (1202), and the resultant dithered portion (dkTF) can then be applied to a control input of switchable devices within the digitally controlled oscillator.

摘要： A novel mechanism for simultaneous multiple signal reception and transmission using frequency multiplexing and shared processing. Multiple RF signals, which may be of various wireless standards, are received using one or more shared processing blocks thereby significantly reducing chip space and power requirements. Shared components include local oscillators, analog to digital converters, digital RX processing and digital baseband processing. In operation, multiple RX front end circuits, one for each desired wireless signal, generate a plurality of IF signals that are frequency multiplexed and combined to create a single combined IF signal. The combined IF signal is processed by a shared processing block. Digital baseband processing is performed on each receive signal to generate respective data outputs. Further, simultaneous full-duplex transmission and reception is performed using a single local oscillator. The phase/frequency modulation of the frequency synthesizer used in the TX is removed from the local oscillator signal for use in the receiver.
