When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

This paper presents a novel Programmable Optically Variable Resistor (POVR) that provides a wide, continuously adjustable resistance range using an LED-LDR (Light Emitting Diode-Light Dependent ...

I–V characteristics of Schottky barrier diodes (SBDs) in low forward bias and reverse bias voltages are critical in low-power and high-speed SBD-based circuits. Accurate modeling of I–V in these ...
