    Hello. If a guard ring is supposed to encircle both inputs of an op amp, on both sides of the PCB, then how are your traces supposed to connect to those 'guarded' inputs? Are you supposed to bring an 'outside' connecting wire into the guarded ring area (rather than using PCB traces to make the connections)?

    Thanks in advance.
