Were you to bias an n-channel JFET as you would a bipolar transistor with a positive ... Thus almost all complex integrated circuit logic devices are FET-based rather than bipolar because of ...

A couple years back we covered a very impressive transistor logic clock which was laid out so an observer could watch all of the counters doing their thing, complete with gratuitous blinkenlights.

A transistor that operates with photons ... B1c has signal gain around a bias point and also gives some logic-level restoration, but requires the bias point to be set very precisely.
