Abstract

In this paper, we demonstrate stochastic resonance (SR) in a double-well potential system that can easily be implemented by a single operational amplifier. First, we propose a bistable mathematical model that is suitable for analog hardware implementation. Then we introduce an analog circuit for the model that is implemented by a single operational amplifier only, and demonstrate that the circuit exhibits the same SR behavior demonstrated in traditional double-well potential systems, through extensive numerical simulations and experiments.
