VCJCN is a nonlinear PN junction depletion capacitance described by a Taylor series expansion in the vicinity of its DC bias voltage, VDD. Its charge-voltage characteristic is give by

where q_{n} are the coefficients of a Taylor-series expansion of
the junction charge function

The current in the capacitor is simply

where i is the current in the controlled source and v is the control voltage. Since
the q_{n} are evaluated at a particular DC bias voltage, DC bias is
implicit in the model. Thus, DC bias must not be included in the circuit.
