Abstract

This work presents a Dual-mode VCO with Noise Filtering. By using dual-mode resonators, an oscillator is designed for two different frequency bands. Also, a properly designed noise filter in the tail current source reduces Phase Noise of LC-VCO. The dual-mode resonator circuit can be changed by adjusting the frequency range with capacitor bank and varactor in both frequency mode. Also, Phase Noise is improved in both frequency mode by current source filter. The VCO has been simulated in a standard 0. 18µ m CMOS process; it covers Tuning Range between 6. 27 GHz-8. 08 GHz and 10. 65 GHz-13. 02 GHz. The simulated VCO achieves a Phase Noise of-120 dBc/Hz from the 6. 83GHz carrier, and-113. 8 dBc/Hz from the 10. 61 GHz carrier at 1-MHz offset, while the Power Consumption is 14. 15 mW from a 1. 5V supply. The calculated figure of merit of this VCO is between-170 dBc/Hz and-184. 31 dBc/Hz.
