Generation of current conveyor based oscillators using nodal admittance matrix expansion

The residual stress in a polysilicon beam varies throughout its thickness and will cause a freestanding cantilever to curl upwards or downwards. Measurement of stress gradient for cantilever beam MEMS switches was studied by new procedure and its influences on pull-in phenomena of cantilever beam type were studied. The effect of non ideal anchors of fixed–fixed end type MEM switches were investigated in. The Generalized Differential Quadrature Method was used as a high order approximation to discretize the governing nonlinear differential equation yielding more accurate results with a considerably smaller number of grid points. Further, the results obtained were compared with other existing empirical and theoretical models.
