feedbacklatch-upphase-marginA power-efficient, voltage gain enhancement technique for op-amps has been described. The proposed technique is robust against Process, Voltage and Temperature (PVT) variations. It exploits a positive feedback-based gain enhancement technique without any latch-up issue, ...
Negative feedback: Vout= AV× Vin/ (1 + | AV× B |) Although an op-amp has a very high open-loop gain, it is difficult to use because of its frequency dependence (see Section 2.2). Therefore, an op-amp is generally used with negative feedback. Negative feedback causes...
With this positive feedback system the overall gain would then become (2.107)Af=Av/(1−β⋅Av) Positive feedback therefore increases the overall system gain. If indeed the product β· Av is made equal to unity then the overall gain becomes infinite. Positive feedback, however, is ...
Every year when I receive the message from Editors Dave and David that it is once again time for Positive Feedback writers to turn in our three Writer's Choice Awards for the year, I reflect back on my year in audio, the products I've written about for Positive Feedback, and my ...

They felt motivated to exclusively breastfeed as their current child was healthier, stronger and got ill less often. “I have two children one who is HIV positive and this one who is HIV negative. I think I transmitted the virus during breastfeeding to the first one since I gave the ...
The output of the regulator is fed into a voltage follower to avoid any loading effects and the output of the op-amp is injected into the top of the feedback resistor network. This has the effect of modulating the voltage to a precise degree without additional loading on the output. ...
However, internal processes may also be important in maintaining kelp forests through feedback mechanisms18,20,21. One internal mechanism could be the capacity of kelp to elevate seawater pH via their photo- synthetic activity22–24. The diel range in seawater pH within some kelp beds can be ...
