Combining Gates Logic gates can be combined to perform any computation. There are millions of them in a computer chip. But let’s see a very simple application of the AND gate.

Importantly, the new biological logic gates are also modular, meaning they could be fitted together to make different types of logic gates and more complex biological processors.

Rise time measurement for a SN7410N, 7.1nS Logic gates are optimised for fast transitions, and should be correspondingly quicker than the 2N3904 we considered earlier.

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

Their work allowed them to build a synthetic biological logic gate that could one day be used to modify cellular functions. The research has been published in PNAS.

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

The common CMOS gates in Figure 1 have aninput threshold voltage in which the output swingsfrom logic zero to logic one, and vice versa. The thresholdvoltage depends on the supply voltage (Figure 2 ...

In this paper, a Floating Gate Field Effect Transistor (FGFET), which has a structure similar to a floating gate memory cell transistor that has been widely used in the past and is highly applicable ...
