Healthcare PCB for ECG Front Ends: Keeping Patient Inputs Quiet at the Cable Boundary

A Healthcare PCB for ECG monitoring may pass a bench check with a short laboratory lead and still become noisy when the production patient cable is attached. The production cable changes pickup area, shield current, connector parasitics, and the route by which common-mode energy reaches the analog front end. This is a design-review scenario for...
