Bipolar junction transistors as switches : Worksheet. Question 1: Solid-state switching circuits usually keep their constituent transistors in one of two modes: cutoff or saturation.
Explain what each of these terms means. "Cutoff" refers to that condition where a transistor is not conducting any collector current (it is fully off). "Saturation" means that condition where a transistor is conducting maximum collector current (fully on). Follow-up question: is there such a thing as a state where a transistor operates somewhere between cutoff (fully off) and saturation (fully on)? Electrical Engineering. Mike's Electric Stuff.
