ABSTRACT:
A sensing circuit. The circuit includes an integrator to sense charge release from a passive electronic device and a comparator to interpret the charge release as one of at least two data states. The circuit also includes a compensation module to generate a compensation signal as needed and a self-timing module to adjust timing of the integrator sensing based upon a predefined voltage level.
