| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To meet ever-increasing demands for computing power in data centers, data rates over 50Gbps/signal (e.g., OIF CEI-56G-VSR)will eventually be required in wireline chip-to-chip communications within and between servers. This paper shows a 56-Gb/s receiver front-end suited for baud-rate clock recovery. Sharing the comparators for the data decision and phase detection minimizes the number of comparators in the front-end and reduces the power consumption. The front-end has a continuous-time linear equalizer followed by a 1-tap speculative decision-feedback equalizer. The front-end operates at 56Gb/s with a bit error rate of less than 10-12 with a 0.4UI margin in the bathtub curve. It occupies 0.27mm2 and consumes 177mW of power from a 0.9-V supply. | |
