Power efficient LIDAR

Abstract:

Described examples include an integrated circuit having an analog-to-digital converter operable to receive an input signal derived from a light signal and convert the input signal to a digital received signal, the analog-to-digital converter operable to receive the input signal during at least one window. The integrated circuit further has a receiver operable to receive the digital received signal, the receiver operable to determine a distance estimate of an object from which the light signal is reflected based on the digital received signal. In an example, the window locations are chosen to correspond to the locations of maximum slope in the signal.
