The schematic and subcircuit look like this..SUBCKT VC_RES2_10K 1 2 4 5 Current controlled voltage source: F Current controlled Current Source. But because GRES is a current output device, we rearrange the law as I = V / (R x Vc). This example is from the Dependent (Controlled) Sources chapter of Ultimate Electronics Book.It shows a DC Sweep simulation where the current through the I1 component depends on a current .5*I(R1.nA) elsewhere in the circuit.. will only need the analog and the source library.) . . In this case the first source is swept over its range for each value of the second source. D( ) is the derivative with respect to time. For all cases, including the nonlinear case (POLY), refer to your PSPICE users guide. Give the junction between the R and C the Alias of Vout using the Net Alias tool as shown below. 175 V_SNS senses a current between the 2 nodes P & M.The ccvs source (H0) receives as CDF Parameter "Name of voltage source" this very name V_SNS (in the schematic shown as vref), and so transfers the sensed current to the ccvs. PSpice will show that Gunthard Kraus, (prof. For any current-controlled dependent source, a dummy voltage is needed in series with the source so PSPICE can determine the current through the source. LTspice Help in CHM from Linear.
