For this week’s QSPICE schematic capture, we have “Miracle” by our friend and frequent schematic capture contributor Alexander Bordodynov. “I found some interesting patterns.” Please send any submissions to me at tim.mccune@qorvo.com. (Schematic Capture Post #073)
I’ve been intrigued by this phenomenon since I learned about a 1951 I.R.E. article “Synthesis of Passive RC Networks with Gains Greater than Unity” by Herman Epstein. That is still behind an IEEE paywall, but I found a newer article, “Revisiting passive RC networks with over unity gain” by S C Dutta Roy, that is free: https://www.ias.ac.in/article/fulltext/sadh/047/0267
