Event-based sensor systems and method for operating event-based sensor systems are disclosed. A sensor system includes an array of sensor elements arranged in columns and rows, wherein each sensor element in the array of sensor elements includes, a detector circuit, an active pixel sensor (APS) circuit, and a dynamic vision sensor (DVS) circuit, the DVS circuit including an event trigger switch configured to control application of a signal on an event trigger line in response to a pixel-specific event trigger signal.

Methods and systems and method for calibrating a time-interleaved Analog to Digital Converter (TIADC) are disclosed. In an example, a method for calibrating a TIADC involves a first calibration phase that involves adjusting for at least one of offset error, gain error, and time skew of M subchannels of the TIADC, and a second calibration phase that is implemented after the first calibration phase and that involves training a neural network to approximate a non-linear function of each of the M subchannels of the TIADC using an output from a reference channel as a ground truth.

Analog-to-information converter and method for performing analog-to-information conversion samples and down-converts N samples of an input multi-band signal using M analog sampling filters or samplers, where N is less than M. The N samples of the input multi-band signal are digitized to produce N digital samples of the input multi-band signal, which are multiplexed into M digital samples of the input multi-band signal. The M digital samples are up-converted and filtered at M digital reconstruction filters to produce a digital multi-band signal, which is processed at a processing unit to obtain information contained in the digital multi-band signal.
