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 ...
The circuit was designed to produce high quality and powerful audio amplifier that would provide 60W-90W power output. MPSA43 – NPN high voltage transistor with low current and high voltage used for ...
Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...
While LDMOS power devices are going to low-cost plastic packages, GaAs HBTs are migrating to larger wafers to cut cost.
