Abstract(in English) | In this report we propose a double-well potential system that can easily be implemented by a single operational amplifier. The system is described by the same dynamics as traditional analog neurons. First, we introduce a potential function obtained from the proposed dynamics, and show the bistable conditions. Then we examine the stochastic resonance (SR) behavior in the system by extensive computer simulations. As in traditional SR systems, we applied sinusoidal inputs to the system where the potential barrier is dynamically fluctuated (but the barrier is not flatten with this input). The stable points can be fluctuated by adding Gaussian noises when the barrier is vanished by the noise addition. As a result of calculations of signal-to-noise ratios (SNR) of the temporal outputs for various noise strength, we found that the system exhibited qualitatively the same SR characteristics as in traditional double-well SR systems. Finally, we show experimental results of an electronic SR system that is implemented by a single operational amplifier, and demonstrate that the circuit exhibits the same SR behaviors as demonstrated in the proposed double-well potential system. |
