Talk:Cut-off (electronics)

Proposed plan for the voice

As I said when I created the stub, this is more a dictionary than an encyclopedia voice: nevertheless I think that adding the following informations will give usefulness to it.

• Cut-off behavior for various electronic device, where a brief description of the "real" meaning of Cut-off in electronic is given.

1. Cut-off in BJTs: a brief (maybe mathematical) description of sub-threshold conduction in bipolar transistors.
2. Cut-off in Field effect transistors including JFETs and MOSFETs.
3. Cut-off in Vacuum tubes,mainly I think triodes.

Suggestions

• some graphs (e.g. BJT, FET, Pentode anode current & transconductance vs g1 voltage, si & Ge diodes) would help
• is apx a well-known abbrev? Just a thought.
• mention of switching transistors and what "cut-off" might be defined as in the datasheet for (say) a BSX20
• mention of push-pull output stages, and the term "cut off" used in, say, Class B (although note that the current might be still a percent or so of the peak current and still be called "cut off" in valve/tube amplifiers, but in transistor amplifiers it will be many, many orders of magnitude below the peak current - close to I_ceo)
• mention I_ceo, I_cbo, V_gs(off) and various leakage terms (linking to more appropriate articles where possible) — Preceding unsigned comment added by Maitchy (talk • contribs) 21:42, 22 May 2014 (UTC)
