But if you need an ungainly inductor in a circuit for its ... We can imagine the inputs of the op amp are open circuits. Whatever voltage is on one terminal, the output will do anything it can ...

Recent research has focused on various applications of active inductors, including voltage-controlled oscillators (VCOs), bandpass filters, and broadband amplifiers, showcasing their versatility ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy ...
