Analog computers use far less power than digital ones. They are also less accurate and less capable of producing repeatable results. Still, since they're often good enough, perhaps more attention should be paid to the analog versions.
Sometimes you can use an IC in a manner not contemplated by the IC's manufacturer. As long as you are not exceeding safe operating area specs, you are probably OK.
The ability to integrate some common analog electronics has been overlooked, creating a wide opportunity for creative IC developers.
What metrics should be established to verify analog performance in general and integrated analog performance in particular? How much testing is not enough and how much is too much?
Pushing devices to smaller geometry produces some good consequences. But those come with other aspects that are less desirable. For integrated analog, there are significant challenges.
