In this paper, we present a calibrated SPICE-compatible mobility function for modeling and simulation of the excimer leaser annealed lower temperature polycrystalline silicon (LTPS) thin film transistors (TFTs). Compared with the conventional mobility function in the well-known RPI TFT equivalent circuit model, the proposed mobility function exhibits accurate results in terms of several DC characteristics. A physical-based model parameter extraction procedure is also proposed for studying the RPI TFT model with the proposed mobility. The model implemented in a circuit simulator for LTPS TFT analog circuit simulation shows reasonable outputs and encounters no any convergence problems.

We investigate the perturbation of the palindromic eigenvalue problem for the matrix quadratic P(lambda) = lambda(2) A(1)* + lambda A(0) + A(1) with A(0), A(1) is an element of C(nxn) and A(0)* = A(0) (where * = T or H). The perturbation of eigenvalues in the context of general matrix polynomials, palindromic pencils, (semi-Schur) anti-triangular canonical forms and differentiation is discussed.
