    Can't understand this power-on-reset comparator circuit (acts like SR flip-flop?)

    Hi everyone, I'm trying to understand this circuit (attached image) as part of an experiment I'm running, based on this video: I understand basic comparator operation and the standard Schmitt trigger configuration (positive feedback creating hysteresis around V+ = V-), but this particular...

    Demodulator design for differentially modulated signal.

    Hello, I am demodulating differential signal using LPF based demodulator. The schematics of the entire system is attached which include diff modulator, coupling capacitors, and demodulator. A modulated signal of 17 Mhz is demodulated. For the demodulator, I designed a 2-stage differential...

    what does this op amp circuit do?

    Hi everyone, could anyone tell me how the circuit works with the op amp that I have attached? I wish I could find the formula that allows me to find Vout as Vin varies. Thank you all. Sorry for the poor English. Long live electronics! :cool:
