Graphene-based EMI shielding for vertical noise coupling reduction in 3D mixed-signal system

Vertical noise coupling caused by the near-field coupling between the RF/analog IC and logic IC is a severe problem in 3D mixed-signal systems. To reduce the vertical noise coupling, graphene is an appropriate material due to its inherent characteristics such as very low thickness, high flexibility, high mechanical strength, and EMI absorbing characteristic… CONTINUE READING
