10Gb/s limiting amplifier and laser/modulator driver in 0.18/spl mu/m CMOS technology

摘要

A limiting amplifier employs active feedback to achieve a bandwidth of 9.4GHz and a gain of 50dB dissipating 150mW. A laser driver uses T-coil peaking and negative capacitance to deliver 100mA at 10Gb/s, while dissipating 675mW. Fabricated in 0.18/spl mu/m CMOS technology, both circuits operate at 1.8V.
