Abstract

A decision circuit IC applicable to 10 Gbit/s optical communication systems has been implemented with AlGaAs/GaAs heterojunction bipolar transistors (HBTs). A 10Gbit/s operation of the D-type M/S flip-flop decision circuit was observed with a clear eye diagram. A good sensitivity of 13mV_pp and a wide phase margin of 300 degrees at 5 Gbit/s were also obtained.
