A Novel Approach for Low Phase Noise Voltage Controlled Oscillator Design based on TSMC ۰.۱۸ um Technology

In this paper, a new structure of Voltage Control Oscillator (VCO) to reduce the phase noise using two plans of a variable voltage capacitor is proposed. The aim of the current paper is to analyse two structure of a completely integrated ۳.۷ GHz LC-VCO based on TSMC ۰.۱۸ um technology. In the first plan for different voltages with variable voltage capacitors in this circuit can be achieved to a suitable phase noise of about ۱۲۵ dB per Hz and in the second plan, a noise of -۱۲۳ dB per Hz is achieved in the deviation frequency of ۱ MHz. Also, the Figure of Merit (FOM) values for the first plan of -۴/۱۸۶ and for the second plan of –۴/۱۸۴ are achieved and the power consumption is ۱۰ mW.
