Method for realizing M/N duty ratio clock signals with chemical reaction networks

Abstract

The invention discloses a method for realizing M / N duty ratio clock signals with chemical reaction networks. The method includes the steps that by means of a circle diagram, 4N chemical reaction networks are provided for realizing an N-phase oscillator, N 1 / N duty ratio phase clock signals are generated, all three kinds of chemical reactions needed by the CRNs are mapped one by one through four kinds of different directed arrows, and the target CRNs can be obtained conveniently and efficiently; support is draw from a circle diagram again, twelve chemical reaction equations are used for building a two-phase oscillation mechanism, and ideal 1 / 2 duty ratio clock signals are generated; the two previous technologies are combined, similar gears of the two circle diagrams are coupled, according to manifestation of the coupling effect on chemical reaction equations, only four chemical reaction equations need to be adjusted slightly, and the target M / N duty ratio clock signals are generated successfully. The method has initiative and pervasive generality, and is popular and easy to understand and capable of being popularized to the design of realizing any rational number M / N duty ratio clock signals with the chemical reaction networks.

Description

technical field [0001] The invention belongs to the field of DNA computing, in particular to the front end of DNA sequential logic design. Background technique [0002] In 2010, David Soloveichik and others proposed "DNA as a universal substrate for chemical kinetics", which proved to a certain extent theoretically: For any formal chemical reaction network (CRNs), we can always easily find the physical realization of its corresponding DNA. That is to say, any CRNs we designed can be mapped to the DNA molecular chain replacement reaction; and the DNA molecular chain replacement reaction can be abstracted as A CRN composed of a series of elementary reactions of the form A+B→C+D simplifies the design. [0003] In 2011, Phillip Senum and others proposed "Rate-independent constructs for chemical computation", indicating that if the chemical reaction network structure is properly designed, the reaction rate of the chemical reaction will not affect the dynamic characteristics of t...

Problems solved by technology

These two oscillators are only mentioned in specific application scenarios, and they have not been raised to the height of "universal generality", and there is no general and convenient method to construct a chemical reaction network with an oscillation mechanism ( CRNs)

And for the 50% duty cycle clock signal that is of great research value in traditional digital circuits, no solution has been proposed
