WebDec 31, 2016 · The FMCW synthesizer employs a differential Colpitts VCO, which covers the complete 60 GHz ISM band with a single frequency tuning curve. Very wide frequency range requires adjustment of the VCO center frequency and output amplitude due to the PVT variations by employing digital automatic frequency (AFC) and amplitude (AAC) … WebNote that the voltage-controlled oscillator (VCO) within the PLL tra-verses a bandwidth (DfVCO)ofD·Dfout = 700MHz over Tm, in the fre-quencystepsof dfVCO = D· dfout = …

For a PLL paired with single band VCO, the largest factor in lock time is the bandwidth of the loop filter. Higher loop bandwidth gives a fast settle time, but also can increase in-band phase noise.

WebJul 4, 2011 · These results are then related to the standard definition of linearity. Measurements from a commercial VCO are finally used to convincingly validate the work, resulting in a simple and practical method to predict the impact of source nonlinearity, as defined by the FSV parameter, on the performance of an FMCW radar system.
