A little of the old, a little of the new—here's a quick brushup on amplifier lore. Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of ...

A class-A amplifier is defined as an amplifier that is biased so that the output current flows at all times. Thus, the input signal-drive level to the amplifier is kept small enough to avoid driving ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

Determine the voltage at the base of the transistor, the resonant frequency, and the peak-to-peak value of the output signal voltage for the class C amplifier in the figure shown ...

Review: Classe CT-2300 is a 300wpc/600wpc (8/4 ohms, respectively) two-channel power amplifier. It's great bench tests,sonic virtues and cool operation makes it a wonderful rack mountable solution. # ...

ALEXANDRIA, Va.—William H. Doherty was an engineer with Bell Telephone Laboratories in 1936 when he invented a circuit that used two tubes running in Class B configuration to act as a linear amplifier ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...
