Will MOSFETs ever completely replace Bi-Polar Transistors?

Does anyone have anythoughts on this?


You cannot remove a BJT from a circuit and replace it with a MOSFET and expect the circuit to perform measure-for-measure at each node.

Well.....you can...... if you're a smoke-mode nutter!

Thanks Airyfor your input, I didn't mean as a direct replacement. I meant with MOSFET technology improving through the years would they displace the BJT.

For instance in audio and instrument applications where noise levels need to be below 2nV/Hz, MOSFETS can't even go there (without being dunked in cryogenic fluid).

Or in High Voltage Applications MOSFET have trouble getting to 1KV

I'm just trying to generate some discussion.. Have a great day
