Implementation Details

VVCN is a nonlinear voltage-controlled current source whose I/V characteristic is described by a Taylor series in the vicinity of its DC bias voltage. As such, it is ideal for use with Volterra analysis or with small-signal IM calculations by harmonic balance. The I/V characteristic is

which can be expressed as

where i is the current in the controlled source and v is the control voltage. The gn coefficients are the Gn parameters of the model.

Since the gn 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.
