This op amp has a finite (but very large) open-loop gain, and the Σ voltage is very small. Thus, the very small Σ multiplied (gained up) by the very large A OL gives us the V OUT at precisely the ...

Inspired by Hogervorst et al's current switch idea, a buffered output stage operational amplifier was designed, which has high frequency, high dc gain, and rail-to-rail constant transconductance ...

While an amplifier provides gain, boosts the signal, an attenuator provides loss, reduces the signal. Attenuators are always a compromise and should only be used if absolutely necessary.

Whether you want a desktop DAC and Headphone Amplifier for listening to music or modernising a hi-fi system, the new Topping DX5 II is now shipping.

A 60-GHz digitally controlled phase-inverting variable gain amplifier (PIVGA) is presented, with a gain control range from -9.4 to 6 dB, and a 180° phase inversion. Four digitally controlled nMOS ...
