Simulation shows that the QVCO provide quadrature phase outputs across the whole tuning range.
The QVCO was designed and fabricated in the TSMC 0.18 [micro]m 1P6M CMOS technology.
Figure 7 shows the measured frequency spectrum at 10.52 GHz of the QVCO, and the output power is -2.95dBm.
The figure of merit (FOM) is a useful performance measured used to evaluate the performance of a QVCO relative to its alternative QVCOs.
where [[omega].sub.o] is the oscillating frequency, [P.sub.DC] is the DC power consumption of the measured QVCO. The phase noise is a crucial important parameter, in Equation (2) the phase noise L{[DELTA][omega]} decreases as the power consumption increases to enhance the strength of carrier power.
A prototype Colpitts cross-coupled QVCO has been proposed and successfully implemented in the TSMC 0.18 [micro]m 1P6M CMOS technology; and it is designed to operate in the 10.0 GHz frequency band and has the figure of merit of -189.7 dBc/Hz.
