Available in PDF, EPUB and Kindle. Book excerpt: Our study also showed that the lumped element approach can be used even for circuits operating well above 100 GHz. A PLL tunable from 45.9 to 50.5 GHz was also implemented in 0.13-[mu]m CMOS process. The power consumption was reduced to 57 mW by using an LC-oscillator based injection locked frequency divider (ILFD) while the operating frequency range is increased by tracking the VCO and ILFD self oscillation frequencies. These results indicate the feasibility of implementing millimeter-wave applications using low-cost CMOS technology. With more advanced CMOS processes, it should be possible to extend the frequency to submillimeter or THz range.
