Abstract :
A passive frequency quintupler using a symmetric accumulation MOS varactor is demonstrated for the first time in CMOS. The broadband (0.65-0.73THz) quintupler with an on-chip antenna fabricated in a 65-nm bulk CMOS process reaches a setup limited peak Effective Isotropic Radiated Power (EIRP) of -22dBm at 726GHz, and a minimum conversion loss of 34dB. This highest order multiplier realized in CMOS has the highest EIRP among any lens-less silicon based signal generation circuit operating above 500GHz.
