Abstract

This paper proposes a compact realization of a core-coupling technique for millimetre-wave (mm-wave) push-push CMOS LC voltage-controlled oscillators (VCOs). The target is to achieve phase noise (PN) performance improvement by maintaining a wideband continuous frequency-tuning-range (FTR) for FMCW radar applications. The VCO cores are superharmonic injection-locked on a common tail node. Three VCOs are fabricated in a 22 nm fully depleted (FD) silicon-on-insulator (SOI) CMOS technology: Single-Core, Dual-Core and Quad-Core. All implementations have the same core design. Measurements show the expected PN improvement for the multicore VCOs compared to the Single-Core VCO.
