  • Grounding layout question

    Hello all. Did a new project and I wonder if You may suggest a grounding points placement for the negative supply in my actual circuit. The sketch is the layout of actual job I did. The components are placed in actual layout position . Just I wonder if there are mistakes or may optimize the wiring of negative supply returns please ? Thanks

    The circuit as it is did not show any sign of noise issue but I.m not to sure about the negative supply return to the ground bus position - as it share both negative bias and CCS inverter in same time- please ? Any thoughts? Thanks.
