I want to circuit modeling rate equation using pspice.
For example :
c1*dv1/dt = v1/a - v2/b + c*v1*v2
that each term refer to a current and v1 and v2 refer as node voltage.
c1*dv1/dt ====> current of a capacitor
v1/a====> current of a resistor
v2/a====> current of a resistor
and my question:
how can I model the last term?
can we use a VCCS that depend on 2 nodes?
thanks for your attention
Yes, should work if you have Pspice A/D. I think you'd need
2*EVALUE (for v1/a and v2/b), 1*EMULT (v1*v2), another EVALUE to get (c*v1*v2), and then 1*GSUM to add/subtract the 3 terms.
