Comparator and method for operating the comparator

摘要

The comparator according to the invention comprises a difference amplifier (DA) connected to a current mirror (CM) and a series connection of a first transistor (P4) and a second transistor (N5) connected between a first and a second operating potential (VDD, GND), wherein the control input of the first transistor (P4) is connected to the difference amplifier (DA) and the current mirror (CM). The comparator further comprises an inverter (INV2) connected to the first operating potential (VDD) and to the outputs of the first and second transistor (P4, N5). A third transistor (N6) is connected between the second operating potential (GND) and the output (NET2) of the difference amplifier (DA) wherein the control input of the third transistor (N6) is connected to the output of the inverter (INV2). <IMAGE>
