Nexxim Simulator > Current Source, Single-Frequency FM (Netlist Only)at Single-Frequency FM Current Source Netlist FormatThe format for a single-frequency-modulated current source is: Ixxxx n+ n- SFFM ( vo va [fc [mdi [fs] ] ] ) n+ and n- are the positive and negative nodes, as for the DC current source. The unlabeled parameters in parentheses are positional. Parameters vo and va are required. Parameters fc, mdi, and fs can be omitted, but the parameters must be entered in the order shown. To guarantee that a given parameter is interpreted correctly, all parameters to the left of it must be present.
SFFM Current Source EquationThe shape of the SFFM current waveform is given by the equation: output = vo + va ´ sin[(2p ´ fc ´ time) + mdi ´ sin(2p ´ fs ´ time)] SFFM Current Source Netlist ExampleI1 15 21 SFFM (0 1e-6 20K 5 1K)
