摘要：
Circuits for processing radio frequency (“RF”) and microwave signals are fabricated using field effect transistors (“FETs”) that have one or more strained channel layers disposed on one or more planarized substrate layers. FETs having such a configuration exhibit improved values for, for example, transconductance and noise figure. RF circuits such as, for example, voltage controlled oscillators (“VCOs”), low noise amplifiers (“LNAs”), and phase locked loops (“PLLs”) built using these FETs also exhibit enhanced performance.
