Abstract
The transimpedance amplifier is realized in a 0.18μm CMOS technology. The TIA uses a shunt-shunt feedback topology, differential TIA because it reaches a higher bandwidth than a conventional one. The TIA also has a variable gain to increase the bandwidth of theamplifier . The TIA has a maximum gain of 73 dBΩ, bandwidth 3.1GHZ, bit rate 5Gb/s and input-referred current noise of 5 pA/√Hz. Eyejitter at bit rate 5Gb/s equal to 5ps (peak to peak).
