millimeter-wave frequency operation have been reported recently [1-3]. Potential applications for such silicon ICs include: Gb/s communication (e.g., 60 and 120GHz bands), long-range collision avoidance radar for automobiles (77 to 79GHz), and radio imaging (94GHz). Implementation of mm-wave transceivers in baseline CMOS technology is attractive because of the potential for both low cost in volume production and RF/baseband co-integration. A mm-wave LO source should provide quadrature (I/Q) outputs to the RF transceiver with simple phase and amplitude tuneability, sufficient output swing to drive a mixer, and adequate spectral purity. Low power consumption is desired for portable applications especially if antenna arrays are used, as multiple LO generators may be needed. A low-power tripler provides the final LO
