We were recently tipped off to quite a resource — on the Texas Instruments website, there’s a page where you can view and ...

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 ...

Here, a power amplifier circuit has been designed using MOSFET to produce 100 W output to drive a load of about 8 Ω. Here, a power amplifier circuit has been designed using MOSFET to produce 100 W ...

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 ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

The Platina Stream, developed alongside the Integrated, brings Quad’s legacy into the streaming era with flagship ESS Sabre DAC architecture , precision clocking, and isolated digital and analog ...

The TEAC AX-505 may have a footprint no larger than a sheet of A4 paper, but it has the heart of a lion with 115W per channel into 4Ω. The heart of a great audio system is a superb amplifier. The ...
