Synthesis of RF CMOS Low Noise Amplifiers

A stand-alone design automation tool tailored for RF CMOS LNA design is presented. Rather than relying on commercially available circuit simulators such as Spectre or Hspice, the presented synthesis tool is self-contained with its own built-in modules for faster performance evaluation. Silicon- verified RF device models are incorporated into the synthesis procedure for accurate parasitic modeling. To validate the proposed approach, an LNA circuit operating at 900 MHz is synthesized and fabricated in a 0.25 mum CMOS technology. Measurement results are presented which shows the viability of the proposed synthesis tool.
