How does a transistor work: the basicsA transistor can be considered as two P-N junctions placed back to back. One of these, namely the base emitter junction is forward biased, whilst the other, the base collector junction is reverse biased. It is found that when a curr...
Even if the EMI concept is well known it is often considered only when the final application does not work as expected on paper, sometimes it is too late to add corrections. Wireless devices increase day by day, and thus, EMI is increasingly ...
Various configurations of a single transistor amplifier are possible. Common emitter circuit, input loop, and output loop have passed the emitter of the transistor Common base circuit, the input loop, and output loop have passed the base of the transistor Common collector circuit, input circuit, ...
Ebers-Moll explanation does appear widely in textbooks, but it certainly isn't widely learned. If it had been learned, then people wouldn't get angry when they hear that transistors are voltage-controlled; that the collector current is proportional to the voltage across the base-emitter junction...
This electronics video tutorial provides a basic introduction into the common emitter amplifier which uses a NPN bipolar junction transistor. This video explains how to calculate the voltage gain, current gain, and power gain of the CE amplifier circuit. ...
The resistance reflection rule for a common-collector configuration can be found through the same method used to solve the same parameter for a common-emitter amplifier. You’ll get a low input resistance for the common-collector confi...
Linear-amplifier output stages are directly connected to the speaker (in some cases via capacitors). If bipolar junction transistors (BJTs) are used in the output stage, they generally operate in the linear mode, with large collector-emitter voltages. The output stage could also be implemented ...
A BJT is one of the most common types of transistors and can be either NPN or PNP. This means a BJT consists of three terminals: the emitter, the base and the collector. By joining these three layers, a BJT can amplify an electrical signal and switch the current on and off. ...
No, it does not "function through switching". In such a regulator, mosfet is partialy conducting, like a controlled resistor. So it is dropping required amount of voltage. Also as a consequence it is dissipating power: voltage dropped x current. That's why it is not very efficient, especi...
Because the VCOM voltage of every display is set individually during production, a nonzero collector-emitter saturation voltage does not have an important effect on the circuit performance. During production of the display, if the VCE(sat) of a transistor is different from the nominal value, the...
