Independent Sources 2



 
Symbol Examples
1. For DC analysis a constant 1V voltage source, and for transient analysis a 5V 50% dutycycle 1MHz square wave, rising at 100ns with a rise/fall time of 10ns:
   value: 1V PULSE(0V 5V 100ns 10ns 10ns 490ns 1us)

2. For DC analysis a constant 5V voltage source, and for transient analysis an undamped 1V (peak to peak) sine of 100KHz, starting at time 0:
   value: 5V SIN(0V 0.5V 100KHz 0s 0)

3. For DC and transient analysis a constant 5V voltage source, and for AC analysis a 1V (peak to peak amplitude) source:
   value: 5V AC 1V

1. A constant current source of 5 Amps both for DC and transient analysis:
   value: 5A

2. For DC analysis a constant 5A source, and for AC analysis a 2A (peak to peak amplitude) source with 90 degs phase shift:
   value: 5A AC 2A 90

These are the transient source formulas:

PULSE(t) = v0 @ 0+n*per .. td+tr+n*per, v1 @ td+tr+n*per .. td+tr+pw+tf+n*per,
   v0 @ td+tr+pw+tf+n*per .. 0+(n+1)*per,   n: 0, 1, 2, 3,...

SIN(t)= vo @ 0 .. td,   vo + va exp(-(t-td) theta) sin(2 pi freq (t + td)) @ td .. end

EXP(t) = v0 @ 0 .. td1,   v0 + (v1 - v0)*(1 - exp(-(t - td1)) / tau1)) @ td1 .. td2,
   v0 + (v1 - v0)*(1 - exp(-(t - td1)) / tau1)) - (v1 - v0)*(1 - exp(-(t - td2)) / tau2)) @ td2 .. end

PWL(t) = v0 @ 0,   v1 @ t1, .., vn @ tn .. end

SSFM(t) = vo + va sin(2 pi fc t + mdi sin(2 pi fs t))
