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

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Traditionally, tube power amps were all point-to-point (PTP) wired or of stripboard construction. Components were wired to a long tag board, which was then mounted under a metal chassis. From the tag ...

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 ...
