Conclusions

power consumption and L(λ) is the phase noise at the oscillation frequency. The low phase noise and low power consumption result in high FOM in this work, and the calculated FoM of each work are listed in Table 16.

4.5 Conclusions

In this future work, we simulated a K band frequency with X band CMOS QVCO. Low phase noise and high FoM is the main design goal in this K band VCO. The power supply is designed as 1.5V for measurement consideration, and the buffers operating at K band consume large power. The simulation results reveal that low power consumption (15.81mW) and low phase noise (-112 dBc/Hz @ 1-MHz) is accomplished in K band. However, some prototypes such as transformers still benefit the performance of a VCO [40]. These prototypes will be the feature study for us.
