摘要

Abstract: This paper describes the characteristics and performance of a high speed, burst mode compatible receiver for optical bus or packet communications. It employs a Si bipolar differential transimpedance amplifier, a threshold tracking control circuit, and a dc-coupled ECL compatible quantizer (decision circuit). To cope with intermittent data packets, the threshold control circuit can capture data amplitude and set the logic threshold in about 1 ns. Using an avalanche photodiode, the typical receiver sensitivity is $MIN@37.5 dBm (10$+$MIN@9$/ BER) at bit rates up to 900 Mb/s, with a dynamic range of 23 db for both pseudo-random and burst-mode signals. At 1 Gb/s, the sensitivity is $MIN@35 dBm. With a worst case reset time $LS 100 ns for the threshold control circuit, this receiver can be used for optical bus applications where data signals with varying optical power are employed. !6
