1. An apparatus for use in measuring low power signals, the apparatus comprising:

  • an integrator, wherein the integrator receives an original low power signal from a signal source and integrates the signal over multiple integration periods;

    an analog-to-digital converter having an analog input coupled to an output of the integrator, wherein the converter digitally samples the integrator output more than two times during each integration period to obtain multiple digital samples; and

    a processor coupled to a digital output of the analog-to-digital converter, wherein the processor determines the original low power signal using the multiple digital samples.
