Özet

As RF IC Design has become more prevalent and more demanding, the need for a more precise VCO phase noise model has arisen. For both MOS and bipolar VCO's new formulas are still being proposed to model the phase noise, which is a key factor for a precise oscillator. In this paper, a previous phase noise model for a Bipolar VCO [1] is refuted and the formulas developed for MOS VCO phase noise calculations [2] are adapted to Bipolar VCO. Then, the results are compared and some conclusions are drawn for the comparison of these oscillators. © 2006 IEEE.
