I have an instrumentation amp circuit similar to that shown in this appnote but with the first stage of the instrumentation amp made out of discrete opamps. The layout has to be done in a single layer (except for the power) with the GND plane. I am concerned with routing two Rg traces to the switch and the resistors. With the best placement I could come up with, they end up forming a relatively big loop around the amp's input pins and a few input components attached to them. I wonder whether this is a problem? Thanks.
