Abstract :
Experimental results for a gigabit Ethernet-compatible photo-receiver circuit generating CMOS logic level are presented. A single-ended preamplifier is combined with a multi-stage differential postamplifier with inverse scaling to increase bandwidth. Circuits are realised in 0.25 μm CMOS, dissipating 26 mW or less. The analogue portion of the receiver operates at 2 μA average input current at 1.25 Gbit/s, increasing to ~10 μm when CMOS levels are generated. A maximum speed of 2.1 Gbit/s is reported for the analogue portion
