“…Although randomness and noise are beneficial in some instances (population heterogeneity being a well-known example [12]), by and large, cells have evolved the means to control biochemical noise through regulatory mechanisms (such as negative feedback) to ensure the robustness of biochemical networks [13]. Indeed, in the context of electrical circuits, negative feedback is a well-known noise-reduction mechanism used in devices such as amplifiers and oscillators (see [14] for a review and important references).…”

We study the stochastic kinetics of a signaling module consisting of a two-state stochastic point process with negative feedback. In the active state, a product is synthesized which increases the active-to-inactive transition rate of the process. We analyze this simple auto-regulatory module using a path-integral technique based on the temporal statistics of state-flips of the process. We develop a systematic framework to calculate averages, auto-correlations, and response functions by treating the feedback as a weak perturbation. Explicit analytical results are obtained to first order in the feedback strength. Monte Carlo simulations are performed to test the analytical results in the weak feedback limit and to investigate the strong feedback regime. We conclude by relating some of our results to experimental observations in the olfactory and visual sensory systems.

The effort to resolve linearity issues led to the discovery of feed-forward and negative-feedback principles in 1924 and 1927, respectively, both by Harold Black [55,56] of Bell Telephone Laboratories. All these early inventions consolidated the AM broadcasting industry, and even though the FM modulation was invented in 1933 by E. Armstrong and essentially modern FM transmitters were installed as early as 1940, AM remained the dominant method for RF broadcasting until 1978 when finally the FM exceeded AM in number of listeners.…”

Abstract-We propose and theoretically and experimentally demonstrate a novel tunable spurious-free single-loop optoelectronic oscillator (OEO) with low drift and low-phase noise. In the proposed transposed-frequency OEO (TF-OEO), a nonreciprocal bias unit and an optical phase modulator in a fiber Sagnac interferometer function jointly as an intrinsically drift-free intensity modulator, which improves the long-term drift. Besides, a transposed-frequency low-noise filtered amplifier is used which replaces the conventional radio frequency (
