Abstract: The disclosure is directed to a frequency synthesizer circuit including digitally controlled oscillator (DCO) and an injection locked digitally controlled oscillator (ILD). The ILD outputs a signal with a frequency that is some fraction of the frequency of the DCO output signal and locked in phase to the DCO output signal. The frequency synthesizer circuit drives the ILD with the same modulation input signal that drives the DCO, with the modulation input signal scaled to account for any mismatch between the gains of the DCO and ILD. Driving the ILD with the same, scaled modulation signal as the main DCO minimizes the frequency offset between the DCO output signal and the divided natural oscillation frequency of the ILD. Minimizing the frequency offset makes the lock of the ILD more robust and reduces jitter contribution from the ILD.

Abstract: Methods and devices providing Positive Logic biasing schemes for use in a digitally tuning capacitor in an integrated circuit device are described. The described methods can be used in integrated circuits with stringent requirements in terms of switching time, power handling, noise sensitivity and power consumption.

Abstract: According to an embodiment, a receiver includes a voltage controlled oscillator, a frequency-to-digital converter and an input sensitivity controller. In the voltage controlled oscillator, input sensitivity relative to a baseband signal is controlled based on an input sensitivity control signal. The voltage controlled oscillator oscillates at a frequency controlled by a voltage of the baseband signal to generate an oscillation signal. The frequency-to-digital converter performs frequency-to-digital conversion of the oscillation signal to generate a digital signal. The input sensitivity controller generates the input sensitivity control signal based on the digital signal.
