Electronic computer circuits consisting of a large number of connected logic gates of the same type, such as NOR, can be easily fabricated and can implement any logic function. In contrast ...

This opens an avenue for three-dimensional polymer micro-electronics, where large-scale circuits can be designed and integrated directly into the three-dimensional structure of woven fibres.

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at ...

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are ...

Many electronic devices today are dependent on semiconductor logic circuits based on switches hard-wired to perform predefined logic functions.

Biological organisms perform complex information processing and control tasks using sophisticated biochemical circuits, yet the engineering of such circuits remains ineffective compared with that of ...

Electronics is a great opportunity to develop an essential engineering skill, which is to design by parts, build and test by parts, and to methodically diagnose what is or isn't working. The course ...

The electronic pest repeller generates powerful ultrasonic signals to repel pests. Logic probe tester Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can ...

However, the power to these bistable circuits cannot be switched off without losing their data. This inability to turn off power is a fundamental problem for energy consumption in CMOS logic systems.

Logic gates are implemented using diodes or transistors acting as electronic switches; most gates are made from field-effect transistors (FETs), particularly metal–oxide–semiconductor field ...

A device containing a pneumatic logic circuit made from 21 microfluidic valves could be used as a new type of air-powered computer that does not require any electronic components. The device could ...
