Patterned Ground Shields For Silicon RFICs Part 4: How Does the Ground Shield Work?

2014-01-08 13:48:00| rfglobalnet Downloads

You might have noticed, in spite of the title of this series, we have discussed the current induced in the RFIC silicon ground rather than the patterned ground shield that designers add to reduce the current in silicon. As I mentioned in Part 1, we must understand our enemy before we can deal with our enemy. We now understand our enemy.
