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.

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 ...

The performance of high unity gain-bandwidth current gain-based CMOS operational amplifiers fabricated in a 1.5-/spl mu/m CMOS digital process is discussed. High unity-gain bandwidth was achieved by ...

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 ...
