P-N junction in semiconductors
This post is covers the topic of pn junction definition. A semiconductor itself does not give any special properties to a semiconductor device. However,…
Large signal diode models
Ideal diode model: describes the diode as an on-off device. The ideal diode can be approximated to the open-circuit and short-circuit device. In the…
Small-signal diode models
The idea of small-signal modelling is that the short-cut part of the current-voltage characteristic of the semiconductor diode is not precise enough in an…
Signal processing diode applications
Limiter A limiter is a diode circuit that is designed to keep voltages at the load in a certain voltage range –Vmin<VL<Vmax, so the…
Electromechanics – main terms
Elelctromagnetic forces are used to produce mechanical effects that are considered in terms of electromechanics. The applications of electromechanics are fairly wide like in…
Transformers and their types
Transformers are most frequent nowadays in the magnetic structures that are in use in many devices. The ideal transformer is a device that sets…
Transistor as an amplifier
A transistor is a three-terminal semiconductor device that can perform amplification and switching functions. The operation of a transistor as a linear amplifier is…
Wireless network definition
This post answers the question "What is definition of wireless network?". The most important part in understanding how wireless technologies work is the fact…
