Analytical modeling of common-gate low noise amplifiers

The exponential growth of wireless portable device market has been increasing the demand for customizable power- efficient transceivers. In this paper, we present an efficient modeling methodology for common-gate low-noise amplifiers (LNAs). Leveraging our models, we designed LNAs to work for different communication standards, GSM at 900 MHz, Bluetooth at 2.4 GHz, and wireless-LAN at 5.6 GHz. Our methodology achieves about 96.45% average accuracy in predicting different figures of merit (FOM) at the center frequency, while it provides Ave orders of magnitude speedup in the design process compared to simulation-based modeling techniques.
