What will I learn?
Gain hands-on expertise in building accurate light detection circuits using photodiodes. Master silicon photodiode principles, reading datasheets, transimpedance amplifier basics, selecting feedback components, biasing techniques, and noise analysis. Then connect with ADCs, refine optics and filters, manage electromagnetic compatibility and safety, and tailor for ambient light sensing, safety barriers, and reflective detection applications.
