A 20-GHz phase-locked loop for 40-gb
A 20-GHz phase-locked loop with 4.9 pspp/0.65 psrms jitter and -113.5 dBc/Hz phase noise at 10-MHz offset is presented. A half-duty sampled-feedforward loop filter that simply replaces the resistor with a switch and an inverter suppresses the reference spur down to -44.0 dBc. A design iteration proc...
