A 10 Gbps Analog Adaptive Equalizer and Pulse Shaping Circuit for Backplane Interface

The speed of serial interface through a backplane channel suffers severe ISI (Inter Symbol Interference) caused by the limited bandwidth of the channel. In order to overcome the bandwidth limit, a pulse shaping circuit or an adaptive equalizer is used. This paper presents the comparison between two approaches. Prototype chip is designed for 10Gbps serial… (More)
