Abstract :
An optical receiver frontend achieving a 5-Gb/s bit-rate was realized in a 0.18 μm CMOS process. The preamplifier has a measured gain of 58.7 dBΩ, an input-referred current noise of 13 pA/√(Hz), and uses a constant-k filter to extend the bandwidth. The transimpedance amplifier (TIA) is followed by a chain of amplification stages with passive offset control. The receiver operates from a 1.8 V power supply, while dissipating only 47 mW (97 mW with the complete test circuitry and buffers). The circuit is housed in a standard CFP24 package.
