Transistors to Gates to Circuits This illustration of a half-adder circuit, which adds one bit to another, depicts logic gates as mechanical switches rather than semiconductor devices.

Other Gate Implementations Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them.

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

While [David] first thought to use 74-series logic circuits directly, a much more versatile solution was to use configurable custom logic — a feature found in AVR DA-series microcontrollers that ...

In this post, we have listed the best freeLogic Gate simulator software for Windows 11/10. Design your own circuit diagrams and simulate them.

Logic gates use digital electronics to implement these functions. Each gate is actually a circuit, typically consisting of transistors and biasing resistors. As an example, the transistor-transistor ...

Engineers choose CMOS/biCMOS logic to be “green” and reduce power consumption. CMOS and biCMOS only draw power on transitions, so those circuits run cool at slow speeds. So why is the board hot?

This is radically different to conventional optical and electrical logic devices that typically perform one logic operation per device, says Zhang. Such simultaneous parallel logical gates could be ...

Combining these gates can produce complex logic capable of responding to multiple inputs. Using RNA toehold switches, the researchers produced the first ribocomputing devices capable of four-input AND ...

Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable ...
