Hello, I’m new here
I’m trying to make a p-n junction capacitance measurement device according to PN Junction Basics and Examples.
So far I know about diode junction capacitance is in different bias conditions(forward/reverse) the depletion region width varies and the diode shows transition capacitance during reverse bias and diffusion capacitance during forward bias.
When a sine wave is applied to a capacitor there is a phase shift between voltage and current, current always leads the voltage by 90degree.
My question is how to measure the junction capacitance of a p-n junction diode using sine wave?
Any idea is appreciated…Thanks a lot.
