Abstract: A fast chirp Phase Locked Loop (70) with a phase preset includes a Voltage Controlled Oscillator, VCO, (12) generating a Frequency Modulated Continuous Waveform, FMCW, (14). The VCO responds to a filtered output voltage (74) of a filter (72) connected to a charge pump (28). A digital controller (82) modifies the FMCW to generate a chirp phase (304) and a return phase (300). The chirp phase includes a first linear change of the FMCW from a start frequency (202) to a stop frequency (204). The return phase includes a second linear change of the FMCW from the stop frequency to the start frequency. A phase preset circuit (86) connects to the digital controller and the filter. The phase preset circuit supplies a phase preset current (98) during a start frequency time (302) preceding the chirp phase. The phase preset current is proportional to a VCO gain of the VCO and inversely proportional to a chirp current during the chirp phase.

Abstract: A fast chirp Phase Locked Loop (70) with a boosted return time includes a Voltage Controlled Oscillator, VCO, (12) generating a Frequency Modulated Continuous Waveform, FMCW, (14). The VCO responds to a filtered output voltage (74) of a filter (72) connected to a charge pump (28). A digital controller (82) modifies the FMCW to generate a chirp phase (304) and a return phase (300). The chirp phase includes a first linear change of the FMCW from a start frequency (202) to a stop frequency (204). The return phase includes a second linear change of the FMCW from the stop frequency to the start frequency. A boost circuit (86) connects to the digital controller and the filter. The boost circuit supplies a boost current (98) during the return phase. The boost current is proportional to a return slope of the return phase and inversely proportional to a VCO gain of the VCO.

Abstract: An electronic device has a capacitive arrangement for controlling a frequency characteristic. The capacitive arrangement has varactor banks having a number of parallel coupled varactors and a control input for switching the respective varactors on or off. A main varactor bank has N varactors and a series varactor bank has A varactors, the main varactor bank being connected in series with the series varactor bank. A shunt varactor bank of B varactors may be coupled to a ground reference and connected between the main varactor bank and the series varactor bank. When a varactor is switched in the main varactor bank, it provides an equivalent capacitance step size (or frequency step) smaller than size of a capacitance step when switching a single varactor on or off. According to the number of varactors selected in the shunt varactor, B, this frequency step can be made programmable.

Abstract: An electronic device has a calibration arrangement for controlling a frequency characteristic of a PLL circuit having a phase comparator having an output for generating a phase difference signal, a voltage controlled oscillator and a divider. The divisor of the divider is programmable, and the oscillator is also directly modulated by an oscillator modulation signal. A modulation unit has a modulation input for receiving a modulation signal and generates the oscillator modulation signal and the divisor such that modulation generates a predefined change of the output frequency and a change of the divisor proportional to said predefined change. The calibration arrangement receives the phase difference signal, and has a ripple detector for providing a detector output signal by detecting a ripple on the phase difference signal correlated to edges in the modulation signal. A calibration control unit adjusts the oscillator modulation signal based on the detector output signal such that the ripple is reduced.
