T-type network design for transimpedance amplifier

Optical network knowledge brief Published 30 Jan 2024

Prepared for preliminary research by the COETZER OPTICAL knowledge desk. Confirm compatibility, loss budgets and installation requirements against current standards and product documentation.

This transimpedance amplifier with a T-network feedback configuration converts an input current into an output voltage. The current-to-voltage gain is based on the T-network equivalent resistance which is larger than any of the resistors used in the circuit. Non-zero amplifier time constant can actually increase TIA bandwidth!! must decrease quadratically! If we integrate the output noise, the upper bound isn't too critical.

The Design of a Transimpedance Amplifier [The Analog Mind]

High-speed transimpedance ampli-fiers (TIAs) serve in the front end of optical communication receivers (RXs). Despite or because of their simple topologies, TIAs pose rigid tradeoffs among their gain,
