    A wireless interface for stacked chips in System-in-a-Package is presented. The interface utilizes inductive coupling between metal inductors. S21 parameters of the inductive coupling are measured between chips stacked in face-up for the first time. Calculations from a theoretical model have good agreement with the measurements. A transceiver circuit for Non-Return-to-Zero signaling is developed to reduce power dissipation. The transceiver is implemented in a test chip fabricated in 0.35 μm CMOS and the chips are stacked in face-up. The chips communicate through the transceiver at 1.2 Gb/s/ch with 46 mW power dissipation at 3.3 V over 300 μm distance. A scaling scenario is derived based on the theoretical model and measurement results. It indicates that, if the communication distance is reduced to 13 μm in 70 nm CMOS, 34 Tbps/mm2 will be obtained.
