Circuit arrangement for a level detector

摘要

The invention relates to level detectors for the acquisition of alternating voltage signals exceeding a predeterminable amplitude. The level detector comprises two inverters in CMOS-technology, connected to each other via a resistor, an input isolation capacitor and some resistors for circuitry. In integrated circuits which contain inverters in relatively large numbers, otherwise unused inverters can be used in an advantageous way for the construction of level detectors.
