Ta 9.7 a 622mb/s 4.5pa/√ √ √ √ √hz Cmos Transimpedance Amplifier*

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 0.6μm CMOS exhibits 4.5pA/√Hz average input noise current, 622Mb/s data rate, and 8.7kΩ transimpedance gain while dissipating 30mW from a 3V supply.
