V_exp

Exponential voltage source

 Description The V_exp component models a rising and falling exponential source.
 Equations $i={i}_{p}=-{i}_{n}$ $v={v}_{p}-{n}_{n}={V}_{1}+\left\{\begin{array}{cc}0& t<{\mathrm{TD}}_{1}\\ \left({V}_{2}-{V}_{1}\right)\left(1-\mathrm{exp}\left(-\frac{t-{\mathrm{TD}}_{1}}{{\mathrm{\tau }}_{1}}\right)\right)& t<{\mathrm{TD}}_{2}\\ \left({V}_{2}-{V}_{1}\right)\left(1-\mathrm{exp}\left(-\frac{t-{\mathrm{TD}}_{1}}{{\mathrm{\tau }}_{1}}\right)\right)+\left({V}_{1}-{V}_{2}\right)\left(1-\mathrm{exp}\left(-\frac{t-{\mathrm{TD}}_{2}}{{\mathrm{\tau }}_{2}}\right)\right)& \mathrm{otherwise}\end{array}$
