Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

Many improvements to the follower circuit have been proposed over the years. The White cathode follower doubles the output current and makes the transfer function more linear. 1 Adding a common-base ...

While LDMOS power devices are going to low-cost plastic packages, GaAs HBTs are migrating to larger wafers to cut cost.

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...
