Question 228: Semiconductors and Logic Gates

Question

For the forward biased diode characteristics shown in the figure, the dynamic resistance at ID = 3 mA will be __________ $$\Omega$$.

Accepted Answer

$${R_d} = {{dV} \over {di}} = {1 \over {{{di} \over {dv}}}} = {1 \over {{{5 - 1 	imes {{10}^{ - 3}}} \over {0.75 - 0.65}}}}$$
$$ = {{100} \over 4} = 25\Omega $$
