Abstract

We present three front-end ICs implemented in 0.6 /spl mu/m CMOS process that meet or exceed the specifications for 1.25 Gb/s fiber-based gigabit Ethernet. The two-stage differential transimpedance amplifier utilizes bondwire based inductive peaking to attain 1.1 GHz bandwidth. The quantizer employs novel modified Cherry-Hooper architecture to achieve a 52 dB dynamic range and 1.5 GHz bandwidth. The laser driver features on chip automatic laser power control circuitry and provides up to 40 mA of modulation current at 1.25 Gb/s.
