A 16-Gb/s Backplane Transceiver With 12-Tap Current Integrating DFE and Dynamic Adaptation of Voltage Offset and Timing Drifts in 45-nm SOI CMOS Technology

This paper presents a 16-Gb/s 45-nm SOI CMOS transceiver for multi-standard backplane applications. The receiver uses a 12-tap DFE with circuit refinements for supporting higher data rates. Both the receiver and the transmitter use dynamic adaptation to combat parameter drift due to changing supply voltage and temperature. A 3-tap FFE is included in the source-series-terminated driver. The combination of DFE and FFE permits error-free NRZ signaling at 16 Gb/s over channels exceeding 30 dB loss. The 8-port core with two PLLs is fully characterized for 16 GFC and consumes 385 m W/link.
