The Metal-Oxide-Semiconductor Field-Effect Transistor, or MOSFET for short, is similar in many ways to the junction FET (JFET). Both are voltage-driven unipolar devices that depend...
Field Effect Transistors (FET’s): Field Effect Transistors (FET’s) are unipolar rather than bipolar devices, and this gives them certain properties that are superior to those...
We were having trouble finding an exact replacement transistor while repairing a piece of equipment. Figuring that an exact replacement was going to be impossible...
Oscillators based on the bipolar junction transistor (BJT) are the subjects of this article. Previous articles in this series have included articles on the characteristics...
Transistors are the key components in many different kinds of audio preamplifiers, amplifiers, and tone-control circuits. Recent articles in this series have discussed the operation...
În acest articol, vă voi arăta cum să construiți un amplificator audio cu integratul LM386. Am construit prezentat numeroase circuite de amplificatoare dar majoritatea...
Bipolar Transistor Basics In the Diode tutorials we saw that simple diodes are made up from two pieces of semiconductor material, either silicon or germanium...
All capacitors have a maximum voltage rating and when selecting a capacitor consideration must be given to the amount of voltage to be applied across...
Dr. John Bardeen(left), Dr. Walter Brattain(right), and Dr. William Shockley(center) discovered the transistor effect and developed the first device in December, 1947, while the three...
Along with the solid-state diode, the point-contact transistor–invented in 1947 at Bell Labs–started the semiconductor revolution and has gone on the become one of the...
