RF specification driven by Multi-Objective Optimization Method

This paper presents a novel method for an optimal distribution of the specification of an RF receiver to its blocks for a given architecture. The novelty of this approach resides in the fact that it offers optimal and feasible solutions, thanks to a nonlinear multi-objective optimization. As demonstrated by examples, the proposed algorithm provides, based on the solution chosen, feasible design parameters for a classic CMOS cascode Low Noise Amplifier (LNA) with LC tank load. The entire methodology has been applied for IEEE 802.15.4 and DVB-SH standards. Finally, with the obtained parameters we implemented the LNA in a CMOS 150 nm process.
