Abstract:

Disclosed embodiments relate to sensing states and changes of states of a signal and sensors for the same, including but not limited to, autonomous sensors. Such sensor may include an analog signal threshold detection circuit, a state detection circuit, and a measurement circuit. The analog signal threshold detection circuit may be configured to alternately assert and de-assert a threshold detected indication in response to an input signal and a state thereof. The state detection circuit may be configured to generate a signal state indication about a state of the input signal. The measurement circuit may be configured to generate a measurement in response to assertions of the threshold detected indication and the signal state indication, such as a count, a slew rate, or a frequency. In some embodiments, disclosed sensors may have programmable thresholds for sensing the signal states and changes therein.
