Model Order Reduction for the extraction of small signal equivalent circuit models of RF-MEMS
نویسندگان
چکیده
A reduced order model for the small signal analysis of micromechanical structures (MEMS) has been extracted by applying model order reduction (MOR) to their finite element models. The low-order model conserves the accuracy belonging to the finite element method, while drastically reducing the computational time. Moreover, it gives a description of the device’s terminal behaviour and can therefore be employed for circuit and system level simulations of MEMS devices. Keywords—MOR, electromechanical coupling, harmonic pre-stressed analysis

متن کاملCMOS RF Modeling and Parameter Extraction Approaches Taking Charge Conservation into Account
A charge conserving small-signal equivalent circuit with very simple and accurate parameter extraction method for a three-terminal CMOS RF model is presented. We found that significant errors in circuit performances can be obtained if charge conserving non-reciprocal capacitances are not properly considered. It is also found that one accurate large-signal I-V model is enough to be used for DC, ...
