Abstract

A technique for generating multiple mm-wave carrier frequencies is introduced, using simultaneous subharmonic injection locking of multiple VCOs to a single reference frequency. A prototype of 30GHz and 50GHz subharmonic injection-locked VCOs is realized in a 90nm digital CMOS process and able to lock from 2nd to 8th harmonic of the reference frequency with locking range reaching 5.6GHz. Simultaneous locking to the 3rd and 5th harmonics of a 10GHz reference signal is also demonstrated.
