An array of 4 complementary LC-VCOs with 51.4% W-Band coverage in 32nm SOI CMOS

CMOS VCOs have been implemented for mm-wave applications.LC-VCO is attractive for VCO arrays. It uses an LC-tank and its area is minimal and highly scalable. The use of state-of-the-art nanometer CMOS technology is essential to retain high-speed design margin for mm-wave circuits and provisions are required to make the complementary LC-VCO more scalable and manufacturable against the process variability and technology uncertainty.
