ABSTRACT:
A negative input voltage comparator that compares a negative input voltage signal against a positive voltage signal in a circuit, such as an integrated circuit. The negative input voltage signal is effectively isolated from the circuit by means of a series resistor in the base-emitter circuit of a transistor which is connected in the output leg of a current comparator.
