I have a basic circuit with diode (D1N4002), resistor R=100 Ohm, and a DC voltage source.
I have set three different temperatures in Temperature (Sweep). Default variable for X Axis is the voltage source, and when trying to change it to V(D1) (using Plot - Axis settings) which is a diode voltage, it gives the error:
ERROR(ORPROBE-3217): Only 1 expression allowed for the X variable.
My simulation profile is set as following:
DC Sweep
Primary sweep
Sweep variable - Voltage source - Name: V1
Sweep type - Linear - Start value: -10V - End value: 10V - Increment: 0.01V
Temperature sweep
Repeat the simulation for each of the temperatures: -75 25 125
My question is how to get diode characteristic (or any other characteristic) Id=f(Vd) when multiple temperatures are used in the same simulation?
Also, how to indicate what trace belongs to what temperature, determine and display the treshold voltage for each trace?
For the set point positioned at Vd=0.8V at temperature 25 degree Celsius and for voltage increment dVd=+0.1V or dVd=-0.1V, determine the dynamic resistance of a diode and display it on the diagram.
Could someone show the steps for this simulation?
Note: This is not homework. I am practicing for exam.
Note: I am using OrCAD Capture CIS Lite 16.6.
