I've gone through every pdf on the net, nothing is clear. They are all written from an engineers perspective. If you could share the math behind the schematic then that would give me something to start with.

To get an inverted output, should i add another opamp following the previous with the output from the first to inverting pin of the second ? or is there a better way to do it with one opamp ?

He could use an nFet too...
i haven't used junction-fet for DC amplification . . . other than four quadrant multiplier . . . ← but this assumed analog or smooth varying signal . . .
? Do you have some digital switching example circuit -- it would be interesting to see
