There are two parts of guard rings - the one in the silicon (wells, doping profiles - to provide a barrier against a minoity carrier injection), and another one in the BEOL (Back-End-Of-Line) - metallization that ties guard rings to the power/ground nets (contacts, M1/M2/M3/..., vias, etc.). WebJan 9, 2014 · Sample MINI-DIP and SOIC op amp PCB guard layouts ... So, the guard ring may only be necessary on the op amp PCB side. In the case of the follower stage (right), the guard trace must be routed around the negative supply at Pin 4, and thus Pin 4 to Pin 3 leakage isn’t fully guarded. For this reason, a precision high impedance follower stage ...
