Request details about application resistance ranges
editDoes the linearization technique only improve voltage range or does it also increase resistance range? Request that the linearization example mention more specifics of typical applicable resistance range per JFET. Any ways to extend resistance ranges (can be limited special non-linear curves/taper)?108.47.10.190 (talk) 22:52, 12 December 2018 (UTC)
Clean up examples and references to missing images
editIn the "Non-linearized VCR design" section there are references to non-existing figures, for example "The simulation below bears this out." or "(Figure 7)". Some parts even look like they were copied and pasted from some book. Also, the calculation example in the same section "Non-linearized VCR design" is messy and cannot be easily followed. I would suggest deleting that. IlarioGelmetti (talk) 09:19, 16 June 2023 (UTC)
Complete list of missing figures
editAs previously noted, several figures are mentioned but not included in the article. Here is the complete list:
- Section "Non-linearized VCR design":
The ramp simulation, below, reveals that the drain-to-source resistance of the JFET is fairly constant (about 280 ohms)… etc
(simulation figure is missing)
- Section "Linearized VCR design":
The linearized VCR ramp simulation, below, indicates that the VCR resistance is constant at approximately 260 ohms… etc
(simulation figure is missing)
...
The simulation below, which uses a 3000-ohm drain resistor, illustrates that the VCR can be successfully used at fairly high input voltage input signals.
(simulation figure is missing)
- Section "Distortion considerations":
For example, the simulation below shows a significant amount of visual distortion… etc
(simulation figure is missing)
...
On the other hand, a simulation of a linearized VCR design shows very little distortion when a 8 V peak-to-peak input signal is applied (Figure 7).
(simulation figure 7 is missing)
All these figures should be added as soon as possible to complete the article and make it more readable. --Centoesettecento (talk) 10:10, 8 January 2025 (UTC)
