Hi everyone! I'm Buse. I'm trying to control a motor speed for a personal project. You can find the schematic of the circuit I found on a book. This circuit works with only the PID parts constructed. My problem starts when I add the other parts. For example, U1 opamp (top left) is supposed to...
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.

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...
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...
