Field Effect Transistor · The PN junction has two dominant feature which are: 1. Injection of minority carriers with forward bias The first point is used to construct BJT i.e....

Many of the input signals have desired frequency, waveform but this signals cannot be used because of its small amplitude. This is because the circuits or the devices need desired...

Hi all, I did my final year project on " Jig for the refrigerator PCB and its analysis in LABVIEW". While the project I published a research paper in IEEE...

BIPOLAR JUNCTION TRANSISTOR A bipolar junction Transistor or BJT or transistor is a small electronic device which can be used either as a amplifier or a switch. It consist of...

1. The output from the rectifier circuits is not purely DC but consist of some amount of AC component into it. This AC component is known ripples. 2. These ripples...

The rectifiers discussed are uncontrolled rectifiers. The elements used here are diodes. this cannot be controlled externally. hence called as uncontrolled. Controlled rectifiers uses semiconductor switches such as thyristors, MOSFETS,...

The main difference in half wave and full wave rectifier is that the complete cycle is utilized in full wave rectifier. Alternate half cycle is inverted and thus a unidirectional...

The rectifiers are broadly classified into two types viz: Half Wave rectifier and Full wave rectifier. Lets discuss Half Wave rectifiers today. Circuit of Half wave rectifier: 1. It basically...

Numerical on current , amplification factors of transistors Some basics: 1. Generalized expression for collector current: IC = α IE +IC0[1-e(Vc/VT)] Where VC is the negative and is very large...

Transistor current components (Very very Important) 1. Current conduction in N-P-N transistor is because of electrons and that in P-N-P is due to holes. The conventional flow of current is...
