An RF inductorless quadrature voltage controlled oscillator (QVCO) with more than 6GHz of tuning range is described. Significant area savings are possible with this architecture compared to traditional LC-tank QVCOs, and the circuit can be operated at frequencies near the f T of the transistors utilized. The proposed high frequency QVCO design can be fabricated in a lower cost technology since it does not require monolithic inductors or high-Q varactors. A new method of tuning the QVCO stabilizes the output power over the tuning range. At 13 GHz phase noises of -79.81 dBc/Hz and -84.27 dBc/Hz at offsets of 600 kHz and 1 MHz were simulated. The integrated circuit was designed to operate from a 3.3V supply, and will be fabricated in a 47 GHz silicon germanium bipolar process. ©2004 IEEE.
