The top circuit, in the diagram above, is a half-wave rectifier and you can see the circuit’s effects on a sinusoidal signal. What is the bottom circuit and how would it effect a sinusoidal input?

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

Beware! The behavior of a part outside its operating specifications is not always predictable. Beware! The behavior of a part outside its operating specifications is not always predictable. In my ...
