Exponential Voltage Source - Model exponential pulse voltage source

Library

SPICE-Compatible Sources

Description

The Exponential Voltage Source block represents 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:

• V1 is the Initial value, V1 parameter value.

• V2 is the Pulse value, V2 parameter value.

• TDR is the Rise delay time, TDR parameter value.

• TR is the Rise time, TR parameter value.

• TDF is the Fall delay time, TDF parameter value.

• TF is the Fall time, TF parameter value.

Dialog Box and Parameters

Initial value, V1

The value of the output voltage at time zero. The default value is 0 V.

Pulse value, V2

The asymptotic value of the output voltage when the output is high. The default value is 0 V.

Rise delay time, TDR

The rise time delay. The default value is 0 s.

Rise time, TR

The time it takes the output voltage to rise from the Initial value, I1 value to the Pulse value, I2 value. The default value is 1e-09 s. The value must be greater than 0.

Fall delay time, TDR

The fall time delay. The default value is 0 s.

Fall Time, TF

The time it takes the output voltage to fall from the Pulse value, I2 value to the Initial value, I1 value. The default value is 1e-09 s. The value must be greater than 0.

Ports

The block has the following ports:

+

Positive electrical voltage.

-

Negative electrical voltage.
