    摘要: A frequency synthesizer includes a controlled oscillator configured to extend a temperature range and phase noise of the synthesizer without compromising the frequency coverage of the synthesizer. The frequency synthesizer also includes bias generation circuitry that sets a bias current of a charge pump to reduce bandwidth variations of the synthesizer. The frequency synthesizer further includes switching circuitry to dynamically turn a charge pump on and off to reduce effects of current leakage in the charge pump.

    摘要: A shielded differential inductor forms a high quality factor (high-Q) inductor that is configured to attenuate frequency spurs and/or noise from magnetic coupling generated by electrical structures on or off of a substrate as well as interference received by other components from magnetic coupling generated by the inductor. The shielded differential inductor includes a differential inductor and a shield that substantially isolates the electrical field between the inductor and the substrate to reduce substrate current loss. The shield includes sets of finger structures that extend beyond the width of the inductor and a hub and spoke configuration of ground conductors that connect the sets of finger structures to ground.

The analog receiver has an input for receiving an RF input signal, and an output for providing a digital intermediate frequency (IF) signal. The digital processor has a first input for receiving the digital IF signal, a second input for receiving a clock signal, a signal output for providing an IF output signal, and a control output for providing a clock control signal. The clock synthesizer has an input for receiving the clock control signal, and an output for providing the clock signal, and is controllable to adjust a frequency of the clock signal to a selected one of a predetermined number of frequencies within a predetermined frequency range in response to the clock control signal.
