Description
Summary:Neuromorphism is a state-of-the-art paradigm driving the design of many novel devices, including sensors. The development of such systems, usually involving the implementation of complex mixed CMOS/sensors chips, is constrained by the lack of compact electrical models compatible with the most utilized design tools. This paper proposes a dynamic compact electrical model specifically conceived for bio-inspired applications of giant magnetoresistance (GMR) based magnetic scanning sensors. The model includes blocks for static analysis, frequency sweeps, and transient simulations. The model, written in Verilog-A high-level language, can be directly used in most of the standard CMOS design platforms, such as Cadence.
