Imec has come up with a novel digitally calibrated charge-pump (CP) phase-locked loop (PLL) that can generate high-quality frequency-modulated continuous-wave (FMCW) signals for mmWave radars at low ...
The performance of analogue phase-locked loops (PLLs) has steadily improved with operating frequencies extending to 8GHz and beyond. Recently, digital PLLs based on direct digital synthesis (DDS) have ...
