Working with MosFet’s
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
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...
Transistor Amplifier Design
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 and Multivibrators
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...
Practical Transistor Circuits
More Power Amplifiers: Today the easiest way to build a low- to medium-power audio amplifier is to pick an integrated circuit (IC) amplifier from a...
Audio Amplifier Basics
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...
Power Amplifier
An audio power amplifier can boost weak signals from a tuner, CD player, or tape deck to fill a room with sound. This article focuses...
Common Collector Amplifier
Common Collector Amplifier: BJT amplifiers are still widely used in modern electronic circuitry. This article focuses on practical variations of the common-collector or emitter-follower amplifier...
“Bipolar Basics” – Part 2
The Bipolar Junction Transistor (BJT) triggered the revolution in modern solid-state electronics in the 1960’s. Although the discrete small-signal BJT has since yielded to the...
