Exponential Voltage Source

Exponential pulsed voltage source.

exponential voltage source

Description

The Exponential Voltage Source unit is a voltage source whose output voltage value is an exponential pulse as a function of time and is independent of the current through the source.

The following equations describe the output current as a function of time:

where

- corresponds to the Initial value, V1;
- corresponds to the Pulse value, V2;
- corresponds to the value of the parameter Rise delay time, TDR;
- corresponds to the value of the parameter Rise time, TR;
- corresponds to the value of the parameter Fall delay time, TDF;
- corresponds to the value of the parameter Fall time, TF.
