Hi ,
Can you please exlain me where the reverse biased diode leakage occurs and please give me an explanation about the path of the reverse current ,as to how it flows and when the leakage stops . And similarly please explain me about sub treshold leakage current too
Reverse bias diode are source-bulk and drain-bulk. There is some current flows through channel even if Vgs <Vt, called subthreshold current. Where it flows, check Fig3 in below PDF. **broken link removed**
