Abstract: A predictive sensor readout is suitable for coupling to a sensor. The predictive sensor readout includes a sampling circuit, a predictor, and a preset circuit. The sampling circuit is configured to receive and over-sample previously digitized samples of signals previously input from the sensor. The predictor is coupled to the sampling circuit and is configured to receive the over-sampled digitized samples into a signal history and to generate a predicted input from the sensor based on the signal history. The preset circuit is coupled to the predictor and the sampling circuit and is configured to present the sampling circuit to receive the predicted input from the sensor prior to sampling an actual input from the sensor.
