    • A bi-polar modulator that can perform quadrature modulation using amplitude modulators is described. In one design, the bi-polar modulator includes first and second amplitude modulators and a summer. The first amplitude modulator amplitude modulates a first carrier signal with a first input signal and provides a first amplitude modulated signal. The second amplitude modulator amplitude modulates a second carrier signal with a second input signal and provides a second amplitude modulated signal. The summer sums the first and second amplitude modulated signals and provides a quadrature modulated signal that is both amplitude and phase modulated. The first and second input signals may be obtained based on absolute values of first and second modulating signals, respectively. The first and second carrier signals have phases determined based on the sign of the first and second modulating signals, respectively. Each amplitude modulator may be implemented with a class-E amplifier.

    • An apparatus comprising a programmable frequency device adapted to generate a reference clock selected from a set of distinct frequency clocks, wherein the programmable frequency device is further adapted to maintain the same temporal relationship of the triggering edges of the reference clock when switching between the distinct frequency clocks. The apparatus further comprises a phase locked loop (PLL), such as a digital PLL (DPLL), that uses the selected reference clock to establish a predetermined phase relationship between an input signal and an output signal. By maintaining substantially the same temporal relationship of the reference clock when switching between distinct frequency clocks, the continual and effective operation of the phase locked loop (PLL) is not significantly disturbed while changing the reference clock. This may be used to control the power consumption of the apparatus.

    • An embodiment pertains to a phase locked loop (PLL) circuit. The PLL includes a voltage controlled oscillator which outputs a signal at a desired frequency. A phase detector is coupled to an output from the voltage controlled oscillator. The phase detector compares the phase of a signal output from the voltage controlled oscillator (VCO) with the phase of a reference signal. A loop filter is coupled to the VCO and the phase detector. The loop filter has a locking mode of operation for locking the phase of the VCO signal to the phase of the reference signal. The loop filter can subsequently be placed in a tracking mode of operation which adjusts the phase of the VCO signal to track the phase of the reference signal.
    • 实施例涉及锁相环(PLL)电路。 PLL包括以期望频率输出信号的压控振荡器。 相位检测器耦合到压控振荡器的输出。 相位检测器将从压控振荡器(VCO)输出的信号的相位与参考信号的相位进行比较。 环路滤波器耦合到VCO和相位检测器。 环路滤波器具有用于将VCO信号的相位锁定到参考信号的相位的锁定操作模式。 随后可以将环路滤波器置于跟踪操作模式中,该操作模式调整VCO信号的相位以跟踪参考信号的相位。

    • In one aspect, a digital PLL (DPLL) operates based on fractional portions of input and output phases. The DPLL accumulates at least one input signal to obtain an input phase. The DPLL determines a fractional portion of an output phase based on a phase difference between an oscillator signal from an oscillator and a reference signal, e.g., using a time-to-digital converter (TDC). The DPLL determines a phase error based on the fractional portion of the input phase and the fractional portion of the output phase. The DPLL then generates a control signal for the oscillator based on the phase error. In another aspect, a DPLL includes a synthesized accumulator that determines a coarse output phase by keeping track of the number of oscillator signal cycles based on the reference signal.
