使用眼寬偵測之八十億位元速率可適性接收器

Abstract

這篇論文實作了一個使用眼寬偵測之八十億位元速率的可適性接收器，其等化器的係數可以自動調整，並使加法器輸出信號的眼寬達到最大。此接收器是使用40 奈米CMOS 製程，其面積為0.18 平方毫米。在頻道損耗為9dB、18dB 和25dB下，輸出信號的資料抖動分別為34.53ps、43.87ps 和63.64ps，而在頻道損耗為25dB的情況下，經過可適性調整後，所有量測結果的誤碼率皆低於10-11，並有著不錯的抖動容忍度，在100 MHz 的抖動容忍度為360 mUI。此接收器的總功率消耗為84mW，其功率效益比為10.5 mW/Gb/s。

This thesis presents an 8 Gb/s adaptive receiver with eye-width detection. The equalizer parameter of the receiver is automatically calibrated by means of detecting the summer output eye-width which has the maximum eye-opening. The receiver is fabricated in 40-nm CMOS technology with an active area of 0.18 mm2. All the measured bit error rate (BER) are less the 10-11 over a 60cm PCB trace with the channel loss of 25 dB at Nyquist frequency. The measured total data jitter of the receiver is 34.53ps, 43.87ps and 63.64ps while the channel loss are 9dB, 18dB and 25dB, respectively. After adaptation, the receiver has a high jitter tolerance of 360 mUI at 100 MHz while the channel loss is 25dB. The overall power consumption of the receiver is 84 mW which converts to a power efficiency of 10.5 mW/Gb/s at 8Gb/s for the PCI-E 3.0 application.
