Notes
The content of the sub-circuit file (SINV.ckt) associated with this model is shown below. The formula/equation used to provide
this function is declared as part of the netlist-specific entry, under the .SUBCKT line of the file.
*Sine of Voltage
.SUBCKT SINV 1 2
BX 2 0 V=SIN(V(1))
.ENDS SINV
The resulting voltage is the value expressed in radians.
Examples
Consider the circuit in the image above. With respect to the SINV component, the entries in the SPICE netlist will be:
*Schematic Netlist:
XM1 IN OUT SINV
.
.
*Models and Subcircuit:
.SUBCKT SINV 1 2
BX 2 0 V=SIN(V(1))
.ENDS SINV
The effect of the function can be seen in the resultant waveforms obtained by running a transient analysis of the circuit.
