Discrepancy in Diode Simulation Results between LTspice and Standard Test Conditions [closed]
I'm currently working on simulating diodes in LTspice and have noticed a discrepancy between the simulation results and standard test conditions (1000 W/m2, 25 degrees Celsius. The results have been ...

What does the slope of an IV plot for a RC circuit represent?
So this is the circuit I am analyzing, a simple charging and discharging of a 100 µF capacitor:
Just out of curiosity, I ran the simulation, hit the switch to charge the capacitor and took the ...

IV curves of solar cells in parallel and series
When 2 solar cells are in parallel, is it that the final IV curve is the simple addition of Currents (for same voltage) of both individual IV curves ?
My main doubt is what happens in 2nd and 4th ...

What is voltage in I-V curve of a solar cell?
I-V curve of a solar cell is given for a given irradiance and temperature. Given a constant irradiance and temperature, why is the voltage changing in an I-V curve? Is the voltage something that we ...

IV curve arithmetic - reference request
When playing around with electrical concepts in my head, I realized that the IV characteristic of any combination of elements, in series or in parallel, can be computed by simply adding the IV curves ...

Compute diode model parameters from IV curve
I'm working on a project using some 5mm through-hole LEDs that I purchased. I want to simulate my circuit in LTspice before soldering it. However, none of the built-in LEDs in LTspice are close to the ...

Output characteristics of a BJT
While plotting the output characteristics of a CE configuration, the graph between VCE and IC, it shows that when VCE=0,IC=0 My doubt is whether VCE=0 means we are shorting collector and emitter or ...

PMOS + resistor \$I_{DS} - V_{DS}\$ curve
I'm trying to plot the \$I_{DS} - V_{DS}\$ graph for a PMOS and a resistor.
I'm getting this so far:
Weird thing is, what I should get (based on my course) should be something like :
How come the ...

Is there anywhere I can download BJT Transistor I-V data?
Is there anywhere I can download some current-voltage data for a bipolar junction transistor? (It doesn't matter that much which one.)
To explain further, for a simple BJT circuit we have the ...

How to account for additional series resistance of SMU for characterising solar cells?
I have been building a source-measure unit based on a design similar to the DC2591A. I unfortunately cannot share the design, but largely it replicates the DC2591A using slightly different components ...

V-I Tester (aka ASA or Octopus or curve tracer)
I want to build a simple V-I tester and based on this article (or this) I did this easy circuit:
R1 = 560Ω
R2 = 100Ω
R3 = 1kΩ
where R1 and R2 is a voltage divider to set the \$V_{(DUT+V_{R_3})}=1VAC\$...

IV curve has non zero current in open circuit condition
I have an IV measurement program running in LabVIEW, where I measure the IV curve of a photovoltaic module using a programmable electronic load from a quick backward sweep (from Voc to Isc.) I have a ...

PV operation points due to load changes
I couldn't find anywhere what happens to the operation point of a PV cell, when, a resistance (load) connected straight up its output, changes (step) from one value to another. With other words, ...

Doesn't a curve tracer harm modern circuits?
I've read about a thing called a "curve tracer" that you can use to compare known good circuits with bad circuits.
It consists of an AC voltage with a resistor that sweeps from -5 to +5V (or ...
