Editing Electrical termination (section)

===Active===
[[Electronic component#Active components|Active]] terminators consist of a [[voltage regulator]] that keeps the voltage used for the terminating resistor(s) at a constant level.

====Forced perfect termination====

Forced perfect termination (FPT) can be used on [[Single-ended signalling|single ended]] buses where [[diode]]s remove [[Overshoot (signal)|over and undershoot]] conditions. The signal is locked between two actively regulated voltage levels, which results in superior performance over a standard active terminator.<ref>{{citation |url=http://www.t10.org/ftp/x3t9.2/document.91/91-037r0.pdf |title=Forced Perfect Termination |publisher=[[IBM]] |date=1990-08-03 |access-date=2016-12-19}} "FPT is a terminator that [dynamically] self-terminates. One that matches itself to the line perfectly, thereby removing all reflections at the endpoints</ref>
