I_exp

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