Abstract :
High-speed transimpedance amplifiers (TIAs) used at the front end of optical fiber receivers present design challenges in the form of trade-offs between input noise current, speed, transimpedance gain, power dissipation, and supply voltage. This transimpedance amplifier in 0.6 /spl mu/m CMOS exhibits 4.5 pA//spl radic/Hz average input noise current, 622 Mb/s data rate, and 8.7 k/spl Omega/ transimpedance gain while dissipating 30 mW from a 3 V supply.
