摘要： A novel mechanism for gain normalization of a digitally controlled oscillator (DCO) in an all digital phase locked loop (ADPLL)-based transmitter that is operative to split the gain normalization multiplication functionality between a modulating path and a PLL loop. The gain normalization of the modulation loop (referred to as modulation path multiplier) comprises a full bit resolution high precision multiplication function. The gain normalization of the PLL loop, on the other hand, is of significantly lower resolution, hence much lower complexity multiplier logic circuitry is required.

摘要： A novel testing mechanism operative to test large capacitor arrays such as those used in a digitally controlled crystal oscillator (DCXO). The invention is adapted for use in DCXO circuits that employ dynamic element matching in their array decoding circuits. The invention combines the use of DEM during regular operation of the DCXO with a testing technique that greatly reduces the number of tests required. The invention tests the capacitors in the array on a row by row, wherein all the capacitors in a row are tested lumped together and treated as a single entity, which results in significantly reduced testing time. This permits the measurement of significantly higher frequency deviations due to the larger capacitances associated with an entire row of capacitors being tested

摘要： A novel time-to-digital converter (TDC) used as a phase/frequency detector and charge pump replacement in an all-digital PLL within a digital radio processor. The TDC core is based on a pseudo-differential digital architecture making it insensitive to NMOS and PMOS transistor mismatches. The time conversion resolution is equal to an inverter propagation delay, e.g., 20 ps, which is the finest logic-level regenerative timing in CMOS. The TDC is self calibrating with the estimation accuracy better than 1%. The TDC circuit can also serve as a CMOS process strength estimator for analog circuits in large SoC dies. The circuit also employs power management circuitry to reduce power consumption to a very low level.

摘要： A novel apparatus for and method of acquisition and tracking bank cooperation in a digitally controlled oscillator (DCO) within an all digital phase locked loop (ADPLL). The acquisition bits of the acquisition bank are used as an extension of the modulation range. The PLL and TX tuning data are broken up (i.e. apportioned) into acquisition components and tracking components. This permits the use of two different capacitor banks (i.e. the tracking and acquisition banks) for modulation rather than just a single capacitor bank as in the prior art schemes. Incorporating the tracking and acquisition bit varactors, the cooperation scheme of the present invention permits the re-centering of the tracking bank to handle natural frequency drift of the DCO and the widening of the modulation range.

摘要： A novel gear shifting mechanism operative to adjust the loop gain of a phase locked loop (PLL) circuit in a continuous and reversible manner. The loop gain can be increased to widen the bandwidth of the loop and can also be decreased to narrow the loop bandwidth. The mechanism incorporates an α gear shift circuit, a p gear shift circuit and an optional IIR gear shift circuit. The α gear shift circuit comprises a infinite impulse response (IIR) filtering which enables hitless operation of the PLL loop at the occurrence of gear shift events. The α gear shift circuit comprises an accumulator whose output is multiplied by the gain value ρ. The invention enables multiple gear shifts in either positive or negative direction to be achieved by configuring the loop gain variables α and ρ which may be accomplished in software.

摘要： A novel mechanism that is operative to observe and compare the differentiated phase of the reference and variable PLL loop signals using a frequency detector. The resultant phase differentiated error is then accumulated to yield the phase error. The operation of the loop with the frequency detector is mathematically equivalent to that of the phase detector. A frequency error accumulator is used to generate the integral of the frequency error. The frequency error accumulator also enables stopping the accumulation of the frequency upon detection of a sufficiently large perturbation, effectively freezing the operation of the loop as subsequent frequency error updates are not accumulated. Upon removal of the phase freeze event, accumulation of the frequency error and consequently normal loop operation resumes.

摘要： System and method for providing type-II (and higher order) phase-locked loops (PLLs) with a fast signal acquisition mode. A preferred embodiment comprises a loop filter with a proportional loop gain path (proportional loop gain circuit 1115) and an integral loop gain block (integral loop gain block 1120). The proportional loop gain path is used during signal acquisition to provide large loop bandwidth, hence fast signal acquisition of a desired signal. Then, during the PLL's signal tracking phase, the integral loop gain block is enabled and its output is combined with output from the proportional loop gain path to provide higher order filtering of the desired signal. An offset that may be present due to the use of the proportional loop gain path can be measured and subtracted to help improve signal tracking settling times.

摘要： A novel and useful fast hopping frequency synthesizer and transmitter associated therewith. The frequency synthesizer and transmitter incorporates a digitally controlled oscillator (DCO) adapted to operate open loop. Instantaneous frequency switching is achieved by changing an oscillator tuning word (OTW) to imitate the three oscillators of a UWB transmitter. In one embodiment, the DCO can change the frequency instantaneously within the 1/fT of the varactor devices used to construct the DCO. An all digital phase lock loop (ADPLL) is used for offline calibration prior to the start of packet transmission or reception. Any phase shift during the switching is tracked by a digital circuit in the transmitter. In a second embodiment, additional frequency accuracy is provided by use of a numerically controlled oscillator (NCO) that functions to generate a fine resolution complex exponential waveform which effectively shifts the synthesized frequency. A mixer applies the waveform to the I and Q data samples prior to conversion to the digital domain.

摘要： A novel apparatus for a low noise, high isolation, all digital transmit buffer gain control mechanism. The gain control scheme is presented in the context of an all digital direct digital-to-RF amplitude converter (DRAC), which efficiently combines the traditional transmit chain functions of upconversion, I and Q combining, D/A conversion, filtering, buffering and RF output amplitude control into a single circuit. The transmit buffer is constructed as an array of NMOS switches. The control logic for each NMOS switch comprises a pass-gate type AND gate whose inputs are the phase modulated output of an all digital PLL and the amplitude control word from a digital control block. Power control is accomplished by recognizing the impairments suffered by a pseudo class E pre-power amplifier (PPA) when implemented in a CMOS process. Firstly, the NMOS switches of the array have significant on resistance and thus can only draw a limited current from the an RF choke when the input waveform is high. The significant on resistance of the NMOS switches is exploited in the DRAC circuit to introduce power control of the transmitted waveform and permits a fully digital method of controlling the RF output power.
