Noise Analysis Photodiode Transimpedance Amplifier | Calculations & TINA-TI SPICE Simulations

In this video, we will step by step workout the noise analysis of a photodiode amplifier. We will use a transimpedance amplifier using the op-amp OPA827. From the datasheet of the photodiode and the op-amp, we will get the necessary information for our noise analysis. We also check our calculations using simulations in TINA-TI SPICE #tina #spices
