Power Analysis and Optimization Using Nonlinear Modeling of Memristor: A Design Case Study

Ever-increasing power consumption due to continuous increase in circuit complexity in nanoscale electronic circuits and systems design is playing a pivotal role today. The necessity of mitigating higher power consumption issues and exploring different types of power minimization techniques are gaining rising importance. Search and exploration with different emerging circuit design technologies are also of increasing importance. A memristor is one such viable candidate with its inherent ability of low power consumption. Proper modeling and intelligent use of memristors in hybrid mode with CMOS can show a bright direction for future design. Here we tried to focus the light on this issue by inspecting the problem with a specific case study of the Wien-bridge oscillator circuit. The basic nonlinear modeling approach of the memristor is followed. Different configurations of circuit replacement are simulated to bring heterogeneity. Thus, an effort is presented in this paper to identify the proper and judicious use of memristors for power optimization. Simulation results are quite encouraging to predict the appropriate configuration for power reduction properly.
