fast beginning for a b amplifier with basisstromkompensation for fast settling

摘要

The improved Class AB input stage monitors the needs of base current in the slewing transistors 22-25 and supplies that base current with extremely fast and precise feedback loops 90-93. This allows the input stage quiescent current to be very small and gets rid of the non-linearities associated with the lack of base current available to drive the slewing transistors 22-25 in a conventional prior art Class AB input stage. The input stage is a very efficient, low distortion, high small signals and full power bandwidth Class AB input stage. IMAGE
