What are the challenges for real-time biosensing and “edge” analysis? How do gold and gold-silver nanowires address the issue? How these sensors can implement elementary logic functions. Wearable ...

Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

In the early days of digital design, all circuits were designed manually. You would draw K-map, optimize the logic and draw the schematics. If you remember, we all ...

Let's assume that you need to simultaneously look at the inputs and outputs of a 16-bit counter to determine a timing error, but you have only a 2-channel scope – how do you look all of the required ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

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 ...

In last month's “Code Basics” article, starting on page 56 of the September issue, we spent most of our time discussing Class 1 circuits. Now, it's time to switch gears and focus on Class 2 and 3.

Logic Gates are among the important components of a circuit. All the logical operations required to perform a particular task in an electronic circuit are carried by these logic gates. If you are an ...

Field-effect transistors based on carbon nanotubes have been shown to be faster and less energy consuming than their silicon counterparts. However, ensuring these advantages are maintained for ...

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.
