Hello,


I am a beginner PSPICE, in simulation electrical and electronics circuits. I want to simulate a schematic with the program Micro-CAP 12. I want to look for some graphics from a photodiode PIN which is a InGaAs Photodiode IG22-Series, I want to monitor follow parameters:

responsivity (A/W) vs wavelength(nm);
dark current (A) vs reverse voltage (V);
shunt resistance vs. temperature;
detectivity vs. shunt x area;
capacitance vs. reverse voltage;
normalized response (a.u.) vs time (µs)
relative sensitivity (%) vs incident Light Level (mW)


And at the transistor BFP420 I want to monitor some graphics at the following parameters:

total power dissipation Ptot = ƒ(TS);
permissible pulse load RthJS = ƒ(tp);
permissible pulse loadPtotmax/PtotDC = ƒ(tp);
collector-base capacitance Ccb= ƒ(VCB)f = 1MHz;
transition frequency fT= ƒ(IC) f = 2 GHz VCE = parameter in V;
power gain Gma, Gms, |S21|² = ƒ (f) VCE = 2 V, IC = 20 mA;
power gain Gma, Gms = ƒ (IC) VCE = 2V f = parameter in GHz;
collector-base capacitance Ccb = f (VCB) VBE = 0, f = 1MHz;
noise figure F = f (IC) VCE = 2 V, ZS = ZSopt;
noise figure F = f (IC) VCE = 2 V, f = 1.8 GHz;
I do not know how to begin. Please help me. I accept, if is necessary any simulator of circuits.Or only important electrical parameters.
I attach a electric schematic.

Thank you for understanding,

The biggest challenge will be to get an accurate model to carry out some
of the measurements you want to do. A number of these are largely derived
from process characterization of the devices.

I would advise, once you have your hand on the model you take a look at its
definition file to see what is covered, possibly even contact production engineer
at manufacturer to find out what parts of model are complete from the charac-
terization findings versus theoretical equation mashups.


Good luck.


Regards, Dana.
 

Can you help me, to get those graphics of parameters?
 

Post your Micro Cap file, there may be some other users here that can help
with various parts of the problem.

Is this a homework problem ?


Regards, Dana.
 

I am sorry that I answer so late. This is not a homework problem. It is a personal project. That has the role to detect the smoke, with a photodiode.
