Abstract: In certain aspects, a comparator (100) includes a first inverter (110) having an input, an output, and a voltage supply input (112), wherein the input of the first inverter and the output of the first inverter are coupled together, and the voltage supply input (112) of the first inverter is configured to receive a first compare voltage (VI). The comparator also includes a second inverter (120) having an input, an output, and a voltage supply input (122), wherein the input of the second inverter is coupled to the output of the first inverter, and the voltage supply input (122) of the second inverter is configured to receive a second compare voltage (V2).
