SPICE-Compatible Sources
The SFFM Current Source block represents a single-frequency current source whose frequency-modulated output current value is independent of the voltage across its terminals. The following equation describes the current through the source as a function of time:
where:
I0 is the Current offset, IO parameter value.
IA is the Current amplitude, IA parameter value.
FC is the Carrier frequency, FC parameter value.
MI is the Modulation index, MI parameter value.
FS is the Signal frequency, FS parameter value.
The magnitude of the time-independent part of the output current. The default value is 0 A.
The magnitude of the sinusoidal part of the output current. The default value is 0 A.
Frequency of the carrier wave. The default value is 0 Hz. The value must be greater than or equal to 0.
The amount by which the modulated signal varies around its unmodulated level. The default value is 0. The value must be greater than or equal to 0.
Frequency of the modulated signal. The default value is 0 Hz. The value must be greater than or equal to 0.
The block has the following ports:
Positive electrical voltage.
Negative electrical voltage.
