Question
Calculate the forward bias current of a diode when forward bias voltage of 0.4V is applied, the reverse saturation current is 1.17×10-9A and the thermal voltage is 25.2mV.Consider η=1.(1 Point)9.156mA8.23mA1.256mA5.689mA
Solution
The forward bias current of a diode can be calculated using the Shockley diode equation:
I = Is * (exp(Vd/(η*Vt)) - 1)
where: I is the diode current, Is is the reverse saturation current, Vd is the applied diode voltage, η is the ideality factor (assumed to be 1 in this case), Vt is the thermal voltage.
Given: Is = 1.17×10^-9 A, Vd = 0.4 V, η = 1, Vt = 25.2 mV = 0.0252 V.
Substituting these values into the equation:
I = 1.17×10^-9 * (exp(0.4/(1*0.0252)) - 1)
Solving this equation will give you the forward bias current of the diode.
