LabVIEW based HP memristor simulator with hardware connectivity for real time circuit operation

Abstract

Memristor has emerged as fourth fundamental element in electronics. However, all the characteristics and functionalities of a memristor are yet to be understood. Main restriction behind wide spread research on this is lack of availability of a physical memristor. This paper presents an easy way to implement memristor simulator using LabVIEW, a powerful virtual instrumentation platform. Here ideal HP memristor model is implemented. Input signal is taken from a physical function generator. It is interfaced with the LabVIEW using an analog to digital converter (ADC) module. Mathematical model of the memristor is implemented virtually in LabVIEW. Output is shown in Digital Storage Oscilloscope (DSO) which is interfaced with LabVIEW using a Digital to Analog converter (DAC) module. Using this setup, a pinched hysteresis loop in Voltage – Current (V – I) characteristics curve which is the signature of a memristor is observed. Shrinkage of loop area with the increment of input frequency is also been observed which concludes success full implementation of the model. Other Input-output parameters are plotted using waveform graph block in software interface. LabVIEW graphical coding is used for all the necessary programmes to implement the model. Although, here ideal HP memristor model is implemented, it can be easily extended to any other memristor models.
