Memristor is a novel two-port circuit element with a memory, as device that can be used in many applications, such as memory, logic, and neuromorphic systems. As a passive circuit element, the memristor would be a useful tool to analyse circuit behavior via simulation. SPICE model is an appropriate way to describe the real device operation. In this paper, a SPICE model of memristor is incorporated with threshold logic circuit for nonlinear dopant drift. Various window functions have been proposed in nonlinear ion drift memristor devices. The circuit analysis of the proposed memristor models are studied by investigating and characterizing the physical electronic and behavioral properties of memristor device. The simulation output should have a current voltage hysteresis curve, which looks like a bow tie. The loop, maps the switching behavior of the device and makes comparison of these memristor implemented circuit design between different types of memristor window models. The research verifies the proposed threshold memristor model and the possibilities of implementing memristor model in practical analog circuit.
