I've had great success building digital logic with minimized part counts. When I've tried to do the same with analog circuits, I've had more mixed success. I realized that it's because digital logic is transitive (in the algebra sense) but analog is only quasitransitive. That is (assuming you're working in the realm of bits rather than abusing physical limits), in digital logic if circuit A is equivalent to circuit B and circuit B is equivalent to circuit C, you can replace A with C, and keep repeating this process until the circuit is minified. In analog electronics, you run into the sorites paradox.
