  • Abstract
    The coupling of oscillators is reviewed. A new scheme of coupling of VCOs is proposed in which no extra elements are needed to couple the VCOs, which leads to a lower phase noise and power consumption. Based on simulation results, a lock-in range from 15.7 GHz to 18.7 GHz for a divide-by-3, and from 16.4 GHz to 17 GHz for a divide-by-5 were achieved with a 180 nm CMOS technology with a Vdd=1.8 V.
