This paper presents a 67GHz LC oscillator exploiting a three-spiral transformer and implemented in 65nm bulk complementary metal-oxide-semiconductor technology by STMicroelectronics. The three-spiral transformer allows operating with a lower voltage supply, still obtaining good phase noise performance, and achieving a compact design. Measured performances when supplied with 1.2 V are: oscillation frequency of 67 GHz, phase noise ( PN) equal to −96 dBc/Hz at 1 MHz frequency offset from the carrier, power consumption ( PC) equal to 19.2 mW and figure of merit ( FOM) equal to −179.7 dB/Hz. Measured performances when supplied with 0.6 V are: oscillation frequency of 67 GHz; PN equal to −88.7 dBc/Hz at a 1 MHz frequency offset from the carrier; PC equal to 3.6 mW and FOM equal to −179.7 dB/Hz.
