Hello,

My name is Dragos. I am want to use simulator Micro-CAP 12, to simulate some electrical parameters from some electronic components.

From InGaAs-photodiode IG17, I want to measure graphically follow electrical parameters:
-spectral response;
-dark current vs.reverse voltage;
-shunt vs. temperature;
-capacitance vs. reverse voltage;
-responsivity temperature coefficient I;
-responsivity temperature coefficient II;
-sample pulse response.

And at the transistor, which is a BFP420, I want to measure graphically follow parameters:
-total power dissipation Ptot = f(TS);
-collector current vs. collector-emitter voltage IC = f(VCE), IB = parameter;
- DC current gain hFE = f(IC), VCE = 3 V ;
-collector current vs. base emitter forward voltage IC = f(VBE), VCE = 3 V;
-base current vs. base emitter forward voltage IB = f(VBE), VCE = 3 V ;
-base current vs. base emitter reverse voltage IB = f(VEB), VCE = 3 V ;
-collector emitter breakdown voltage VCER = f(RBE), IC = 1 mA ;
-transition frequency fT = f(IC), f = 2 GHz, VCE = parameter;
-collector base capacitance CCB = f(VCB), f = 1 MHz ;
-maximum power gain Gmax = f(IC), VCE = 2 V, f = parameter in GHz;
-maximum power gain Gmax = f(VCE), IC = 20 mA, f = parameter in GHz ;
-noise figure NFmin = f(f), VCE = 2 V, ZS = ZS,opt, IC = 5 / 20 mA ;
-noise figure NFmin = f(IC), VCE = 2 V, ZS = ZS,opt, f = parameter in GH

Or to measure only those important parameters.

Please, can anybody give me some advice, in mathematical parametric electrical behavioral modeling of the analog signal of these components, which here is in general about SPICE?

Thank you for understanding,

Dragos.

So, do you want to measure of do you want to simulate?
And if simulate, why on earth would you want to take a graph from datasheet, process it to make it work inside spice, and then run a simulation to give you back that exact same graph?

Yes. I want to measure graphically those electrical parameters, in the Micro-CAP12 . Can you help me, please? I am a beginner in simulation SPICE.
