Abstract

The comparator has a differential amplifier receiving first and second inputs and producing an output, a first current source adding a first current to the differential amplifier in response to one potential level of said output, and a second current source adding a second current to the differential amplifier in response to the other potential level of said output. The differential amplifier comprises two input transistors having emitters connected in common and a current mirror as a load having an input section connected to the collector of one of the input transistors and an output section connected to the collector of the other input transistor. The first and second current are fed to the input and output sections of the current mirror, respectively.
