It was shown recently [Murali et al., Phys. Rev. Lett. 102, 104101 (2009)] that when one presents two square waves as input to a two-state system, the response of the system can produce a logical output (NOR/OR) with a probability controlled by the interplay between the system noise and the nonlinearity (that characterizes the bistable dynamics). One can switch or “morph” the output into another logic operation (NAND/AND) whose probability displays analogous behavior; the switching is…

Construction of logic gates exploiting resonance phenomena in nonlinear systems

The conventional LSR paradigm is extended to implement higher-level logic architecture or typical digital electronic structures via carefully crafted coupling schemes and to realize morphable logic gates through the Logical Coherence Resonance in excitable systems under the influence of noise.

Emergent noise-aided logic through synchronization.

This article presents a dynamical scheme to obtain a reconfigurable noise-aided logic gate that yields all six fundamental two-input logic operations, including the xor operation, through a stringent measure of reliability.

Enhanced logical stochastic resonance under periodic forcing

Numerical implementation of a VCSEL-based stochastic logic gate via polarization bistability.

The phenomenon of logic stochastic resonance (LSR) is demonstrated, by which the laser gives robust and reliable logic response to two logic inputs encoded in an aperiodic signal directly modulating the laser bias current.

On the dynamics of a single-bit stochastic-resonance memory device

A memory device, consisting of a ring of two identical overdamped bistable forward-coupled oscillators, which may serve as a building block in a larger scale solution to this problem of smaller noise margins and higher error rates is proposed.

It is demonstrated that the array enhanced logical stochastic resonance has a saturating effect at larger array size, and the small or medium array size is good enough for one to obtain reliable logic operation.

Reliable logic circuit elements that exploit nonlinearity in the presence of a noise floor.

It is shown that when one presents two square waves as input to a two-state system, the response of the system can produce a logical output with a probability controlled by the noise intensity, which is a "logical stochastic resonance".

A Fast and Simple Implementation of Chua's oscillator with cubic-like Nonlinearity

This work describes a novel implementation of Chua's oscillator using just four transistors and a battery to produce a cubic-like nonlinearity, which is simple, robust, and capable of operating at frequencies over one thousand times greater than the original Chua't oscillator.

Tuning in to Noise

Two sweeping generalizations can be made about most natural systems: They are intrinsically nonlinear and they operate in noisy environments. Examples abound, ranging from weather systems to
