That's in my PSpice bag of tricks for quick diagnosis. "BUFFn" is
just a unity gain buffer... removes all the bias current problems. In
actual practice I'd build these from MOS, but here I just wanted to
demonstrate the basic idea, devoid of the clutter that would result
with a perfect device-level solution.
