Ring around the inverter

[Dr. Shane] request THE question: What arrived if You connect THE to go out of A inverter logic grid back has THE to input? In theory, he doesn't TO DO sense, but depending on, depending on THE doors physical construction, you go get In A odd State. THE transistor In THE grid will behave differently that they Normally would be, And you go wind up with A amplifier Or A oscillator. You can see THE results In THE video below. In THE second video, You can see What THE odd connection do has THE thermal properties of THE inverter, too.

THE CMOS inverter becomes biased In THE active region, SO he makes sense that he settles down has THE half-way indicate. THE Lifetime inverter East slightly different, but THE delay through THE grid is not it enough has produce A GOOD oscillation. However, A odd number of inverters connected In A ring as This East A path has create A simple oscillator.

While We don't do it suggest This method, he East interesting has see What arrived When You bias different doors This path. We have certainly seen he do using A variety of different inverter types varying Since discreet transistor circuits has inverters on THE die of A IC.

We have seen ring oscillators In A number of shapes. Inverters can Also TO DO THE phase shift part of A crystal oscillator.
