摘要：
A differential transimpedance amplifier used in amplifying optical signals transmitted with a balanced code has a level restore circuit which integrates the digital output of the amplifier and feeds back the result to one of the differential inputs of the amplifier. The feedback signal removes imbalances from the amplifier output. The balanced amplifier output can then be processed by a clock reconstruction circuit to accurately sample the received optical signal with a low bit error rate.
