Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...

Introductory courses on noise in electronic circuits often start by stating the following formula for the open-circuit noise voltage of a resistor: You’ll probably argue that’s a lot of conditions; ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

Chua’s circuit is the simplest electronic circuit that produces chaos—the output of this circuit never repeats the same sequence, and is a truly random signal. If you need a good source of randomness, ...

Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d. Figure 3: ...

Electrical components, like motors close motorA device which spins when current flows through it. Motors are used in fans, food processors and many other devices. and lamps close lampA component which ...
