Noise Analysis Photodiode Transimpedance Amplifier, Calculations 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 opamp OPA827. From the datasheet of the photodiode and the opamp, we will get the necessary information for our noise analysis. We also check our calculations using simulations in TINATI SPICE. 00:00:24 Outline 00:00:48 Part 1: Conversion of Light to Electric Signal 00:03:37 Part 1: Photodiode Model 00:06:29 Part 1: Responsivity vs. Wavelength of Light 00:09:36 Part 1: Junction Capacitance 00:11:19 Part 1: IV Characteristics 00:12:47 Part 1: Transimpedance Amplifier Circuit 00:14:24 Part 1: Transimpedance Amplifier Bandwidth 00:15:23 Part 1: Transimpedance Amplifier Noise Model 00:17:42 Part 1: Photodiode OpAmp Noise Current Sources 00:21:00 Part 1: Thermal Noise Voltage Feedback Resistor 00:21:23 Part 1: Noise due to OpAmp Noise Voltage Source 00:25:02 Part 1: Frequency Parameters 00:27:53 Part 1: SPICE Simulation
