V(OUT) = { V(1,0) + V(2,0) + V(3,0) + V(4,0) }
Example 2: two-input voltage multiplier
This is an example of a device which takes two input voltages and multiplies them together
resulting in a single output voltage.
The representative polynomial expression would be as follows:
Vout = 0.0 + (0.0)V1 + (0.0)V2 + (0.0)V12 + (1.0)V1V2
The corresponding SPICE POLY form would be as follows:
EMULT 100 101 POLY(2) (1,0) (2,0) 0.0 0.0 0.0 0.0 1.0
This could be represented with a single MULT device. For additional examples of a voltage
multiplier device, refer to the Analog Behavioral Modeling chapter of your PSpice User’s
Guide.
Example 3: voltage squarer
This is an example of a device that outputs the square of the input value.
For the one-dimensional polynomial, the representative polynomial expression reduces to:
Vout = P0 + P1·V + P2·V2 + ... Pn·Vn
The corresponding SPICE POLY form would be as follows:
ESQUARE 100 101 POLY(1) (1,0) 0.0 0.0 1.0
This could be represented by a single instance of the MULT part, with both inputs from the
same net. This results in the following:
Vout = (Vin)2
