Methods and apparatus providing an ultra-low power bandgap reference using a clocked amplifier are disclosed. An example apparatus includes a clocked comparator to compare a first voltage to a second voltage when a clock signal pulses and output a comparison signal based on the comparison, the comparison signal being (A) a first signal when the first voltage is higher than the second voltage and (B) a second signal when the first voltage is lower than the second voltage; a monoshot to when the comparison signal is a first signal, output a first pulse; and when the comparison signal is a second signal, output a second pulse; and a charge pump to increase an output voltage when the monoshot outputs the first pulse; decrease the output voltage when the monoshot outputs the second pulse; and hold the output voltage when the monoshot is not outputting a pulse.
