Lecture
This lecture covers the operation of p-n photodiodes, explaining how the reverse current increases upon photon absorption due to the generation of electron-hole pairs. It delves into the importance of the depletion region in transporting charge carriers and discusses the i-V relation of photodiodes under different biasing conditions. Additionally, it explores the limitations of p-n photodiodes, focusing on the impact of the depletion region width on the device's performance.
