For Power Integrity simulation, we calculate Z target as (V * %ripple tolerance)/ Max. Current. In order to avoid over-design and get optimal results: 1. How do I set the % ripple tolerance? 2. Since we test and verify results in EMC lab. I am looking for guides/ formula that correlate between Z target and radiated (and conducted) emission CE mask Best regards, Yosi Zanjiri R&D Value Engineering RAD Data Communications LTd.
