SPICE model of memristor and its application

In this paper, a circuit model of the memristor using SPICE is presented, which expands the hitherto methods to solve the memristor's modeling equations presented by HP lab. This kind of the memristor model can not only be encoded in SPICE and satisfy the properties of the general memristive systems, but also use few components and simulate fast. In order to further explore the nonlinear and switching characteristics of the memristor model, a directly modulated patch antenna with one memristor is designed by using finite-difference time-domain (FDTD) simulator integrated with the nonlinear SPICE circuit solver.
