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...

The open loop amplifier is not practical - once an op amp is pushed to saturation, its behavior is unpredictable. Recovery time from saturation is not specified for op amps (except voltage limiting types). It may not recover at all; the output may latch up. The output structure of some ...
IL-33 is a danger signal that binds to its receptor ST2L to promote tumor progression. This study identifies the IL-33/ST2L positive-feedback loop and the trafficking of ST2L membrane presentation in macrophages that contribute to lung tumor progression.

However, only three can make the final cut, so now for the drum roll announcing my three Positive Feedback Writer's Choice Awards for 2020! Sorry, I just couldn't do it. I just couldn't narrow it down to three. So, after I wrote the above sentence, I sent a message to Editors...
