Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...

Overview of digital logic design. Implementation technologies, timing in combinational and sequential circuits, EDA tools, basic arithmetic units, introduction to simulation and synthesis using ...

One of the hardest things about studying electricity, and by extension electronics, is that you generally can’t touch or see anything directly, and if you can you’re generally having a pretty bad day.

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...

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 digital ...

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 logic high or low ...

Lyric Semiconductor thinks it is probably time to blend analog and digital technology into a new technology they call probability processing. Analog values called pbits that are processed by ...

Living cells make decisions based on information processing genetic programmes. Many of these programmes execute digital functions 1,2,3,4,5,6,7,8. The capability to build synthetic digital systems in ...

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, ...
