Ultra Fast Response AC-Coupled Burst-Mode Receiver with High Sensitivity and Wide Dynamic Range for 10G-EPON System

Abstract

A 10-Gbit/s-class ac-coupled average-detection-type burst-mode receiver (B-Rx) with an ultra fast response and a high tolerance to the long consecutive identical digits has been developed. Key features of the circuit design are the baseline-wander common-mode rejection technique and the inverted distortion technique adopted in the limiting amplifier to cope with both the fast response and the high tolerance. Our B-Rx with newly developed limiting amplifier IC achieved a settling time of less than 150ns, a sensitivity of -29.8dBm, and a dynamic range of 23.8dB with a 2³¹-1 pseudo random bit sequences. Moreover, we also describe several potential B-Rx applications. We achieved better performance by applying the proposed systems to our B-Rx.
