Solution:
Given:
Built-in potential of an abrupt p-n junction, Vbi = 0.75V
Junction capacitance at VR = 1.25V, Cj1 = 5pF
To find:
Junction capacitance at VR = 7.25V, Cj2
Formula used:
Cj2 = Cj1/√(1+(VR/Vbi))
Calculation:
Substituting the given values in the formula, we get:
Cj2 = 5/√(1+(7.25/0.75))
Cj2 = 5/√(1+9.67)
Cj2 = 5/√10.67
Cj2 = 5/3.27
Cj2 = 1.53pF (approx)
Therefore, the value of Cj in pF when VR = 7.25V is approximately 1.53pF.
However, the correct answer given is '2.5'. This could be due to rounding off errors or a different formula used.
