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.
Claims17
A sensing circuit, comprising:
- an integrator to sense charge release from a passive electronic device;
- a comparator to interpret the charge release as one of at least two data states;
- 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.
2 more elements
A timing circuit, comprising:
- a voltage generator to generate a threshold voltage signal;
- an amplifier to amplify a reference voltage signal;
- and
- a comparator to detect when the reference voltage becomes substantially equal to the threshold voltage and to generate a read out signal.
1 more element
A method for sensing output on a passive electronic device, the method comprising:
- predefining a threshold voltage level;
- comparing a reference voltage to the threshold voltage level;
- generating a read out signal when the reference voltage level becomes substantially equal to the threshold voltage level;
- sensing an output voltage level upon reception of the read out signal;
- and
- determining if the output voltage level is one of two data states, producing a first read signal.
