    Collector feedback and output impedance

    Hi there. I found a website that uses Miller's Theorem to analyze a simple collector biased transistor (voltage shunt feedback). There's something about the ouput Z that I don't understand. https://wiki.analog.com/university/courses/electronics/text/chapter-9#example_972_using_miller_s_theorem...

    Implement PFC controller properly to AC/DC converter

    I am trying to implement a PFC controller to AC/DC converter stage, but I have some problems to get the current feedback correctly so the output is more steady state. Also, the waveform have transients in the beginning, it is possible to reduce these transients? I have connected a transistor...

    A Wearable Sound-to-light Display

    Hi there, Someone has posted it online, but I need to explain it more clearly. Take a look in the circuit, 1. First stage of the amplifier looks non inverting inputs are getting voltage drop, using divider R2 and R4, while inverting input is connected with same voltage source droping at R1...
