npub1zdmwgufa05tqfv49tftj3pgawd995dcwkh2z4vpe4l5tne3har6qd3g0vj (npub1zdm…g0vj) In your schematic, it might help to have "dummy" nets to separate grounds to mark separate return currents between two components. There are separate return currents between the gnd of the op-amp and the gnd of the ADC, from the gnd of the op-amp to the signal source, a reference generator and the ADC, the XO and ADC, and the ADC and signal receiver. These should be separated as much as possible. The dummy nets can be rejoined as a single plane after layout.
