Abstract
A semiconductor die comprises a first active device, at least one of a second active device and a passive component, and electromagnetic shielding configured to at least partially electromagnetically isolate the first active device from the at least one of the second active device and the passive component. The electromagnetic shielding includes one of a grounded metal layer and via stack, and a grounded metal layer disposed one of above and below the first active device.
