Use this source to create an exponential waveform.

You must specify a value for the V1 and V2 parameters; The remaining parameters, if not specified, are assigned a default value.

Parameters

Parameter Description Units Default
DC DC Amplitude of the source used in operating point analysis. V or A 0
V1 Initial amplitude of the output with respect to the negative terminal (usually ground). V o A  
V2 Maximum amplitude of the output swing. V o A  
TD1 Rise delay time. The point in time, from t0, when the output begins to rise. This provides a phase shift of the output by delaying the start of the exponential waveform. 0
TAU1 Rise time constant. s TSTEP
TD2 Fall delay time. The point in time, from t0, when the output begins to fall. s TD1+TSTEP
TAU2 Fall time constant. s TSTEP
ACMAG AC Magnitude of small signal voltage or current. Set this if you plan to do a small signal AC analysis based on this source. V or A  
ACPHASE AC Phase of small signal voltage or current. Set this if you plan to do a small signal AC analysis based on this source. If phase is omitted, a value of zero is assumed. degrees  
DISTOF1 Set this if you plan to do a distortion analysis based on this source. Specify the amplitude and phase using space as separator. If phase is omitted, a value of zero is assumed.    
DISTOF2 Set this if you plan to do a distortion analysis based on this source. Specify the amplitude and phase using space as separator. If phase is omitted, a value of zero is assumed.
