Differential output, transformer coupled push-push VCO and divider for 60GHz applications in 90nm CMOS
A push-push VCO with embedded BALUN and resistive CML divider for 60GHz heterodyne transceiver architecture, are presented. The measured VCO second harmonic output frequency is ~44.6–50[GHz], i.e. ~11.4% tuning range. The phase noise at 1[MHz] offset from the carrier, is ranging between −109 to −112[dBc/Hz] and −97 to −100 [dBc/Hz], for f0/2 and 2×f0 outputs, respectively. The circuit works from 1.3V supply and consumes ~20mA current (VCO ~7mA, Divider + Divider buffer~8mA, second harmonic buffer ~3mA). The output power is ~ −13dBm and −20dBm at the f0/2 and 2×f0 outputs, respectively.
