RF MEMS Oscillator Design For integration with SOC Using Order Reduction Methods

Abstract

The recurring tendency of system-on-chip (SoC) to integrate analog or mixed-signal components, and soon micro electromechanical systems (MEMS), on the same chip with digital systems implies the need for new modeling and co-simulation techniques. This is because the current modeling techniques consume an enormous amount of resources: numerical computation, time and designer’s effort. We suggest implementing behavioral modeling of MEMS devices and applying methods of order-reduction (MOR) to these models to save time and effort in both modeling stage and simulation. In this paper, we implemented RF MEMS oscillators behavioral models (mechanical, electrical, and mathematical) and utilized singular values decomposition (SVD) and orthogonal-triangular decomposition (QRD) methods to these models for the purpose of order reduction and rank approximation of the input system. This resulted in improving the simulation time and system resources. Nevertheless, an IP soft-core was recieved in VHDL code for each of these devices to be co-simulated in SOC platform.
