摘要：

This paper presents a formula for predicting the frequency of oscillation of a cross-coupled voltage-controlled oscillator (VCO). The VCO was implemented in a CMOS 0.13 mu m technology. The calculated frequency of operation shows a close agreement with the simulated results. The VCO operates at 10GHz and consumes 490 mu W from a 1V supply. The simulated phase noise at a 1MHz offset is -114.4dBc/Hz resulting in a figure of merit (FOM) of -197.6dB. The VCO can cover a 748MHz frequency range and occupies 0.096mm(2) of chip area. The simulated sensitivity of the frequency of operation and peak-to-peak amplitude due to temperature is 4.58MHz/degrees C and 3.6mV/degrees C, respectively. The sensitivity of the frequency of operation and peak-to-peak amplitude due to power supply is 1.1GHz/V and 1.82V/V, respectively.
