Build a dependent current source in the operating range of the diode in question. The 1N4148 (1N914), for instance, is a 75ma diode. I would build a current source capable of 0 to 50ma. Plot voltage versus current and then replot current versus voltage. Be prepared to plot on log-log or semi-log paper, in order to show the true nature of the curve. Also, be prepared to do several runs for several diodes, and also at several temperatures, because there are variations amongst diodes and also as a result of temperature.
For most accurate reporting, you should measure the diode's temperature during the test runs, because the higher currents will cause it to warm up and change its curve shape.
This would be a good example for a computer controlled test device. Sounds like a project to me????

How do you find IDSS from the characteristics curves of a JFET?
To find the drain-source saturation current (IDSS) from the characteristics curves of a JFET, locate the transfer characteristic curve, which plots the drain current (ID) against the gate-source voltage (VGS). IDSS is identified as the maximum drain current occurring when VGS equals zero (VGS = 0V). This point corresponds to the intersection of the ID curve with the vertical axis (ID axis) on the graph. Reading the value at this point gives you the IDSS for the JFET.

What is meant by a frequency response curve of an acceptor circuit?
A frequency response curve of an acceptor circuit illustrates how the circuit's output amplitude varies with different input frequencies. It typically shows the gain or attenuation of the circuit across a range of frequencies, highlighting its behavior at resonance and in the passband. This curve helps in understanding the circuit's performance, including bandwidth, cutoff frequencies, and how effectively it accepts or rejects signals at various frequencies. Overall, it is a crucial tool for assessing the circuit's filtering characteristics.

What are the three characteristics of a supply curve?
The three characteristics of a supply curve are the slope, shift, and the curve's position. Together they help determine supply and demand trends.

What portion of the volt-ampere characteristics of the diode is linear when is forward biased?
Below the diode's Forward Voltage (Vf) typically 0.7V, the curve is at (roughly) zero. At around 0.5 it begins to curve upward, and at around 0.7V, the voltage drop is almost constant (the curve heads straight upwards to infinity). See link.
