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, ...

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 this column, we take a closer look as to how timing and delays affect our logic circuits. As part of this, we start to consider the timing diagrams presented in data sheets. As I was writing my ...

I find that if I’m trying to make a point with a student or a colleague about a circuit, sometimes the Falstad online simulator is worth a few thousand words. You can draw the circuit, play with the ...

A solid knowledge of logic gates is at the basis of programming and electronics. This is required in any project. Truth tables are a great way to visualize the results of various combinations of ...

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 ...
