Nexxim Simulator > Inductor, Frequency-Dependent (Netlist Only)
Frequency-Dependent Inductor Instance Netlist SyntaxInstead of the standard inductor syntax with a specified inductance value, you can define the inductance by an expression involving the frequency, using the syntax given in this section. The general form for a frequency-dependent inductor instance is: Lxxxx n1 n2 [L=]'freq-dependent-expr' [TC1=val] [TC2=val] [M=val] [SCALE=val] [DTEMP=val] [TNOM=val] [TRAN_EVAL_FREQ=val] n1 is the positive node and n2 is the negative node of the inductor. The current is assumed to flow from n1 through the inductor to n2.
Frequency-Dependent Inductor Netlist ExamplesFrequency-domain analysis L1 1 2 L='1/sqrt(HERTZ)' dtemp=30 TC1R=0.1 TC2R=0.05 Time-domain analysis L2 11 22 L='1/sqrt(HERTZ)' TRAN_EVAL_FREQ=1e8 Notes1. The frequency-dependent inductor is supported only for frequency-domain analyses such as AC and LNA. Running a time-domain analysis such as TRAN on a circuit including a frequency-dependent inductor is an error. 2. The frequency-dependent expression should be enclosed in single quotation marks. The token HERTZ can be used in the expression to indicate the frequency as supplied by the analysis. The circuit frequency is available to the model each time the model equations are evaluated. The label L= is optional. The first unlabeled value is taken to be the inductance. 3. When the parameter TRAN_EVAL_FREQ is provided, Nexxim can run a transient (time-domain) analysis, substituting the value of TRAN_EVAL_FREQ for the variable HERTZ to produce a constant inductance value for the transient analysis.
