Apply Tee Networks to Broaden TIA Required Solutions (Part 2): Loop Gain Plot, Noise, and Single-Supply Operation

Part 2 of the article explores the impact of adding a tee to the op-amp loop gain plot, focusing on loop gain plot modification, noise analysis, and single-supply operation for transimpedance amplifiers (TIAs). The article discusses how the tee network affects output noise and details modifications required for single-supply operation. It also demonstrates the application of the tee network using a JFET input device in a 50-MΩ TIA design. The tee network method allows for adjusting the required capacitance values for easier implementation while considering typical parasitic capacitance on resistors.
