Abstract :
A self-synchronized RF-interconnect technology (SSRFI), based on capacitor coupling and peak signal detection, is presented in this paper. It can be easily implemented in 3-dimensional ICs (3D-ICs) with small coupling capacitors (60 fF) to interconnect vertical active layers. The demonstrated SSRFI system, including both transmitter and receiver, has been designed, fabricated and verified in UMC 0.18 μm CMOS with a verified PRBS (Pseudo Random Binary Sequence) data rate of 3 Gbit/s and a BER (Bit Error Rate) of 1.2×10-10. The core circuit burns about 4 mW from a 1.8 V supply and occupies 0.02 mm2 chip area.
