Study of Memristor with Verilog-A Model
Vijay Singh Baghel and Shyam Akashe

To design any electronic circuits there are three fundamental elements known as Resistor, Capacitor and Inductor and these elements provide relation between four fundamental variables in the circuits. These variables are voltage, current, charge and flux. Resistor, Capacitor and Inductor give the mathematical expression by the use of four fundamental variables and established relations between them but there is no element that relates charge and flux. To relate charge and flux a new fourth fundamental element was invented that give mathematical expression between charges and flux; this element known as Memristor. Memristor is a two terminal passive element that was invented in 1971 by Leon O. Chua. Memristor name indicate that it is a combination of memory and Resistor that is the reason behind its use as a memory and it is nonvolatile in nature that is if power supply is off data will not get lost because it remembers the recent value of charge that has passed through it. Memristor is used in digital circuits, analog circuits and in memory. In this paper design of Memristor model with the help of Verilog-A model in cadence virtuoso tool has been done.

Keywords: Capacitor, Inductor, Memristor, Resistor, Verilog-A.
