Circuit for comparing two voltages, has comparator circuit with comparator having two inputs and output, where supply terminal is provided with output, where output of supply terminal is coupled with input of comparator

摘要

The circuit has a comparator circuit with a comparator (10) having two inputs (101,102) and an output (103). A supply terminal (30) is provided with an output (301), where the output of the supply terminal is coupled with the input of the comparator. The supply terminal in a state changes the voltage that rests against the input. An independent claim is included for a method for comparing two voltages.
