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 ...
In electronics, a Norton amplifier—also known as a current differencing amplifier (CDA)—is a specialized analog circuit that ...

Rega's flagship Mercury and Solis pre/power amplifiers are finally a reality and promise "no-compromise" audio performance
At long last, Rega has confirmed that these top-of-the-range pre/power amplifiers are finally ready: the Mercury ...
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 ...
b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...
In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
The Solis is a stereo power amplifier with hella power. It’s capable of delivering 168 watts (into 8 ohms) or 305 watts (into ...
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 ...
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., ...
