Physical Device Modeling of a Varactor Diode

IEEE Transactions on Magnetics, 2004
Starting with the recipe for the fabrication process of a silicon p-n junction varactor diode, the semiconductor device equations are solved using the finite-element method. The capacitance of the reverse biased diode is extracted using the junction depletion width which is quantified by introducing a depletion factor.
