Abstract: Various embodiments may provide a comparator circuit arrangement. The comparator circuit arrangement may include a preamplifier having a first input configured to be coupled to a first input voltage, a second input configured to be coupled to a second input voltage, and an output configured to generate a preamplifier output signal based on the first input voltage and the second input voltage. The comparator circuit arrangement may also include a switch circuit arrangement coupled to the preamplifier, the switch circuit arrangement configured to deactivate the preamplifier upon the second input voltage exceeding the first input voltage and further configured to activate the preamplifier upon a fall of the second input voltage, and a pull-up circuit arrangement coupled to the output of the preamplifier, the pull-up circuit arrangement configured to provide a boost voltage to the preamplifier output signal for a predetermined duration upon the fall of the second input voltage.
