Abstract

An equation-based method for the optimization and design of single-ended low noise amplifiers (LNA) is presented. The performance metrics of the LNA such as gain, noise figure and input impedance are formulated in terms of the design variables. The parasitics are included early in the design process and optimal LNA designs satisfying the required specifications are found by the optimizer. Optimal LNA designs based on a 0.35 μm CMOS technology obtained by the presented approach are further verified by the spectre simulator of the Cadence design environment. The specifications and performance of the designs are found to be in close agreement, validating the compact optimization technique presented in this work.
