What a beautiful circuit. Recalling my first encounter with op amps as a struggling undergrad, faced with seemingly incomprehensible analog electronics, it was not pretty. I graduated but must note the significance and beauty of these circuits was lost on me. Not surprising university was my last serious encounter with analog electronics. I do slightly regret not using the opportunity to explore and appreciate the elegance of it all. Working with software now, elegance and beauty are seldom the first thoughts that come to mind while debugging code. Maybe Shaw was right, youth is wasted on the young :)
