Hi everyone
I'm designing a wideband receiver with N-path filters.
At the last stage we must use combiner to collect the voltages on the capacitors.
I have designed combiner with 3-stage inverters. To work properly, I added resistor feedback between first and last stage.
But when I run pss analysis, I get convergence error. Without resistor feedback, there is no problem. but when I add the resistor feedback, I get this convergence error:
