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 ...

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 ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

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 ...

Everyone has a chip-of-shame: it’s the part that you know is suboptimal but you keep using it anyway because it just works well enough. Maybe it’s not what you would put into a design that you’re ...

The HiFiMAN SERENADE Wireless DAC/Headphone Amplifier offers lossless streaming over Wi-Fi for $200 less than its predecessor. From Dr. Fang Bian, President and CEO, HIFIMAN Electronics: “The addition ...
