7. Diode parameter:1- Bulk resistance (rB) It is the sum of the resistance values of the P- and N- type semiconductor materials of which the diode made of.rB = rP + rN
8. Usually, it is very small, and given by:Where: VB is barrier potential rB = It is the resistance offered by the diode well above the barrier voltage i.e when current is large. Obviously, this resistance is offered in the forward direction.
9. 2-Junction resistance (rj or rd)It is also known as incremental resistance and is an important parameter particularly in connection with small signal operations of the diode. Its value for forward-bias junction depends on the magnitude of forward dc current.
