Simple circuit Serves as milliohm meter - 04/15/04 EDN-Design Ideas: When I
was recently debugging a design, I discovered that a short circuit existed from a
ground plane to a power plane. I did not have access to a milliohm meter or an
equivalent tester for locating this type of short circuit. So, I logged onto the
Internet to find an easily constructible milliohm meter.....(design idea added 1/05) |
