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 ...

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 ...

The circuit was designed to provide protection to the output of power amplifier thereby protecting the loudspeaker from unwanted noise and other elements. Power Amplifier – a type of amplifier built ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

The D’Agostino New-Generation Momentum Z Monoblock Amplifier is priced a $125,000 USD and available through Authorized Dealers Internationally, Canada, Mexico, and the US.

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 ...

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 ...

At $1,999, the Technics HA-507 is a pure analog headphone amplifier and preamplifier with a balanced/dual mono configuration. Although TEAC’s Reference 500 series includes UD models that combine both ...
