Introduction
Genetic Schmitt Trigger Project Our goal is the realization of a genetic circuit able to implement the functionality typical of an electronic device called Schmitt Trigger.
Pardon me, what do you mean? (AKA Functional Requirements) The main characteristics of this device is to be a “smart” switch. A switch is a device that, given a change in some environmental condition causes an appropriate modification in the output, for instance the output changes from on to off. Often the environmental change represents a modification of value in a parameter (input of switch) that describes the environment. The device switches for a gven value (threshold) of the input. So far so good, however, if the switch input has a value that continually even minimally changes across the threshold, the system will keep going on and off, wasting energy and leaving the system in an unstable state. To avoid all this we need a “smart” switch. Basically, this device switches for two different threshold (High and Low threshold, TH and TL respectively) depending on the history of the system. So, according to the state of the system, the threshold for switching will change. This can solve the instability problem, since the variations that cause instability now must be as high as the difference between the two thresholds (see Figure 1).
