In electrical engineering, an equivalent circuit refers to a theoretical circuit that retains all of the electrical characteristics of a given circuit. Often, an equivalent circuit is sought that ...

While it is hard to imagine today, securing a license to produce transistors was difficult in the early days. What’s worse is, even with the license, it was not feasible to use the crude devices ...

A Wilson current mirror is a three-terminal circuit (Fig. 1 ... the circuitry in which the current mirror is embedded. All transistors have the same current gain β. Q1 and Q2 are matched and they ...

A newly developed transistor device has shown exceptional levels of resilience in tests, performing so well, in fact, that it promises to transform the electronics and gadgets we make use of each day.

Abstract: It has been indicated that there is a growing interest in the possibilities of multiwinding transformers with five windings. The lack of a suitable equivalent circuit for this type of ...

The signal’s envelope is equivalent to its outline ... A biased envelope detector circuit. The amplitude modulated signal is AC-coupled into the base of NPN transistor Q1, which is configured as an ...

Be wary of substituting other power transistors in place of the ones shown in the app circuit. Those NPN & PNP transistors are nice little surface-mount types made by Zetex; they have a very unique ...
