Can you build this circuit and try it out? When i look at your op amps, it looks like the first two will oscillate. I would have to calculate it out but that’s what my gut tells me. What does everyone else think? I think you will have to be very careful in which op amp you chose.
The 22 kHz doesn’t make the PCB layout a transmission line. It’s the rising edge of the 22 kHz signal. If you have a really fast rise time then you could get reflections and you need to treat the circuit as a transmission line. If you just have a point to point a resistor at the output is...
