What I call "Searle's circuit" is what Mike posted. The values are
from "Mike's" circuit. Looking through SEEC v5 (Thornton, Searle,
Pederson, Adler, & Angelo; 1965), I don't find that feedback-triple
configuration at all. (Thornton and Adler were my instructors at MIT;
Solomon did his thesis under Pederson at Berkeley, which is where I
think the configuration originated.)
