Abstract :
The distributed interconnect parasitics within large transistors markedly degrade the output power and efficiency at millimeter-wave frequencies. This paper develops a model for such structures and proposes a layout technique to reduce the effect of source terminal parasitics. The technique is applied to a 60-GHz prototype in 65-nm CMOS technology, raising the output power from 5 to 10 dBm and the drain efficiency from 3.7% to 10.7%.
