lowpass

I have designed a 2nd-order Sallen-Key filter with a 3 kHz cutoff frequency using the OPA4863PWR. I wanted to check whether, similar to ideal vs practical integrators, there are any non-ideal effects that need to be considered here. Specifically, do factors such as finite gain-bandwidth, slew...

Hi everyone, I'm trying to implement this active low-pass filter using a TL072CP. I have simulated it in LTspice, and its behavior is pretty much what I expected. However, when I assemble it on the breadboard and analyze its Bode plot, it appears more like a high-pass filter with poor gain...

Hi. I plan to make a pcb that drives peltier and heating pad. Only one of those works at the same time. Load elements are parallel to capacitors. I have very little space on pcb so it would be nice if I could use only one inductor as it is in screenshot. I know it would be easier just to put...
