Comparator circuit arrangement and method of forming the same

A method of forming a comparator circuit arrangement, the method comprising:

• providing 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;
• coupling a switch circuit arrangement 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
• coupling a pull-up circuit arrangement 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;
• wherein the switch circuit arrangement comprises a reset circuit arrangement coupled to the second input of the preamplifier;
• and
• wherein the reset circuit arrangement is configured to generate a reset pulse in a reset signal upon the fall of the second input voltage.
