Abstract

Transimpedance Amplifier (TIA) plays a significant role in today’s high speed fiber net communication. TIA is the first block in an optical transceiver utilising Visible region of electromagnetic spectrum. For high speed fiber net links, the parasitic capacitance encountered during design and manufacture restrict the bandwidth of operation. This report provides an insight on how to design a high bandwidth TIA for fiber optic communication. The project is focused on designing a high bandwidth, low power TIA. The high bandwidth TIA is designed on the principle of inductive peaking. The entire design of the TIA, was done in Cadence Virtuoso. The process technology is 45 nanometers. The simulation was performed in Analog Design Environment. The simulated results showed improvements compared to the expected results. Keywords: High bandwidth, High gain, low power, low noise.
