The Differential Transimpedance Amplifier Design based 0.18 μm CMOS Technology

摘要

The transimpedance amplifier is recognized in a 0.18μm CMOS technology. The TIA applies a shunt-shunt feedback topology, differential TIA as it grasps a higher bandwidth rather than a conservative one. The TIA additionally has a variable gain to upsurge the bandwidth of the amplifier. The TIA has a concentrated gain of 70 dBΩ, bandwidth 3.1GHZ, bit rate 5Gb/s and input-referred current noise of 5 pA/√Hz. Eye jitter at bit rate 5Gb/sequal to 5ps (peak to peak).
