Circuit for improving noise immunity by DV/DT boosting

摘要

A circuit for suppressing false operation of a level shift circuit due to a noise transient, the circuit comprising a first transistor coupled to a voltage source of the level shift circuit and being coupled to pass a current when a noise transient is present on the voltage source an output terminal coupled to the first transistor providing as an injected signal a current proportional to the current in the first transistor to at least one level shift transistor of the level shift circuit to prevent false triggering of the level shift circuit due to the noise transient.
