Hi,
Confused about the order in which ptap ring and ntap rings used in double guard rings. which one should come in the outer region ? and which one should be inner? and why? I read both way (either p+ outside or n+ outside). Please explain with sufficient reason and why not the other method? If both ways we can use please mention the scenario.
