Abstract
For an high speed communication, a 40GHz VCO was implemented using a 0.11um standard CMOS technology. The mm-wave VCO was designed by a LC type using a spiral inductor, and a simplified architecture with buffers and a smart biasing technique were used to get a high performance. The frequency range of the proposed VCO is 34~40GHz which is suitable for mm-Wave communication system. It has an output power of -16dBm and 16% tuning range. And the phase noise is -100.33dBc/Hz at 1MHz offset at 38GHz fundamental frequency. The total power consumption of VCO including PADs is 16.8mW with 1.2V supply voltage. The VCO achieves the FOMT of -183.8dBc/Hz which is better than previous VOCs.
