I_sffm

Single-frequency FM current source

 Description The I_sffm component models a source consisting of a carrier signal of frequency ${F}_{C}$ frequency-modulated by a sinusuoidal of frequency ${F}_{S}$.
 Equations $i={i}_{p}=-{i}_{n}={I}_{\mathrm{O}}+{I}_{A}\mathrm{sin}\left(2\mathrm{\pi }{F}_{C}t+\mathrm{MDI}\mathrm{sin}\left(2\mathrm{\pi }{F}_{S}t\right)\right)$ $v={v}_{p}-{v}_{n}$

Variables

 Name Units Description Modelica ID $v$ $V$ Voltage drop between the two pins $\left({v}_{p}-{v}_{n}\right)$ v $i$ $A$ Current flowing from pin p to pin n i
