  In this paper, we investigate few memristor-based analog circuits namely the
phase shift oscillator, integrator, and differentiator which have been explored
numerously using the traditional lumped components. We use LTspice-IV platform
for simulation of the above-said circuits. The investigation resorts to the
nonlinear dopant drift model of memristor and the window function portrayed in
the literature for nonlinearity realization. The results of our investigations
depict good agreement with the conventional lumped component based phase shift
oscillator, integrator, and differentiator circuits. The results are evident to
showcase the potential of the memristor as a promising candidate for the next
generation analog circuits.
