A pn junction diode has a reverse bias capacitance Cj=80fF, Cj0=150fF, and a reverse bias voltage of 2 V. What is Vbi?
If you can give a figure for the same than it can be solved easily , also the voltage Vbi is across which terminals ?
i can provide a hint to this question as
there will be voltage across diode and capacitor which will be exactly equal to the input voltage applied .
If you can provide the circuit diagram i can give the exact solution to your query
