Dicode Partial Response Signaling over Inductively-Coupled Channel

摘要

Dicode partial response signaling system over inductively-coupled channel has been developed to achieve higher data rate than self-resonant frequencies of inductors. The developed system operates at five times higher data rates than conventional systems with the same inductor. A current-mode equalization in the transmitter designed in a 90-nm CMOS successfully reshapes waveforms to obtain dicode signals at the receiver. For a 5-Gb/s signaling through the coupled inductors with a 120-μm diameter and a 120-μm distance, 20-mV eye opening was observed. The power consumption value of the transmitter was 58 μW at the 5-Gb/s operation.
