A 0.58-0.61THz Single On-Chip Antenna Transceiver Based on Active X30 LO Chain on 65nm CMOS

A fully integrated 0.58-0.61THz transceiver based on active X30 LO multiplier chain realized for the first time in CMOS above 500GHz. The chip incorporating an on-chip antenna achieves the highest EIRP of -4.9dBm and the highest collected radiated power of -15.1dBm at 607.5GHz with the largest 3dB EIRP BW between 582-612GHz while consuming DC power of 378mW. The chip achieves the lowest NF of 32.6dB or equivalent NEP of 7.3aW/Hz at 605GHz. These results are state of the art among all lens-less Si circuits operating beyond 500GHz.
