A wide variety of synthetic biological circuits have been constructed to endow cells with functions analogous to those of electronic circuits. A long-term goal of these efforts has been to develop ...

An engineer has assembled the most complex logic circuit yet assembled in a single bacterium. The logic circuit, in which genes and the molecules that turn the genes on or off function as logic gates, ...

Fluorogenic DNA aptamers produce light only in the correct structural state, enabling programmable molecular logic, ...

Complex programmable logic devices (CPLDs) contain the building blocks for hundreds of 7400-serries logic ICs. Complete circuits can be designed on a PC and then uploaded to a CPLD for instant ...

In this column, we take a closer look as to how timing and delays affect our logic circuits. As part of this, we start to consider the timing diagrams presented in data sheets. As I was writing my ...
