Abstract

This paper describes a general model for magnetic sensors to be used in portable systems. The model, written using the VERILOG-A language, enables the simulation of fully integrated solution. Physics and magnetic features of sensors are accounted for including second order effect like temperature, parasitic capacitance and contact resistance. The behavioral model obtains first magnetization and cycles completely customizable for the hysteresis calculation. The accuracy is very good without requiring heavy computation. The behavioral model describes magneto-resistances, magneto-inductances, flux-gate and Hall devices. The model is verified by computer simulations in the Cadence-Spice environment.
