Abstract

Fully integrated voltage-controlled oscillator (VCO) is one of the most important blocks in the implementation of a single chip in today's wireless communication system. In this paper design and analysis of the ultra wideband and low phase noise linear LC VCO with low current consumption is presented. The MOS varactor is used to realize a wide tuning range. The phase noise level of the VCO is -117.381 dBc/Hz at 1MHz offset and -127.2 dBc/Hz at 3 MHz offset. The Kvco ratio is about 1.24 GHz/V. The proposed topology gives a linear wide tuning range from 4.29 GHz to 5.29 GHz. Considering a 3.2V supply voltage the DC current consumption is about 3.13 mA and FOM of the proposed VCO is -187.5. This is the significant advantage of this circuit over previous works.
