This article reports a 320-GHz low-jitter and low-reference-spur signal source consisting of an 80-GHz integer-N phase-locked loop (PLL) and a 320-GHz frequency quadrupler. The 80-GHz PLL features a novel dual-path quadrature exclusive-OR (QXOR) technique to cancel the spurs at the reference frequen...
