A 86 MHz-12 GHz digital-intensive reconfigurable synthesizer is presented with 100 kHz to 2 MHz bandwidth. It leverages a 15 pJ/Shot 5.5 ps 14 b coarse-fine TDC and a 6-to-12 GHz dual-VCO set. The 0.28 mm2 synthesizer features simple background calibration, Â¿Â¿ noise cancelation, and digital phase modulation, and consumes less than 30 mW.
