How it works
Initially I just wanted to do an inverter, but then I thought I'll make the inverter much more powerful. The problem with much bigger output transistors is that their gate capacitance increases, and so the inverter is slower. My adding a primary, smaller inverter in front, I get much faster rise times on the big transistors.
How to test
Apply a pulse to analog pin 1 and see it replicated on analog pin 0.
