I've grown the impression that JFETs and depletion mode MOSFETs are not used very much nowadays, especially in new designs.
I know that they need different bias networks, especially as discrete components, so I guess there might be some advantages in using them, but the current trend doesn't seem to corroborate that guess.
Are depletion mode devices being made obsolete by the development of the technology of enhancement MOSFETs? Are there still applications where the use of a depletion device gives distinct advantages, especially as discrete components (I know that depletion mode MOSFETs can be used as active loads in IC MOS technology, so they may still be needed there)?
On a related note, I'd like also to know whether JFETs are still actively used in new designs, since it seems that they could be replaced by depletion MOSFETs (assuming one really needed a depletion mode device for some reason).
