Abstract
Described herein are analog-to-digital converters (ADCs) that utilize time-to-digital converters (TDCs) and a histogram block to generate time-correlated histograms from analog signals. In some implementations, the time-to-digital converters determine time intervals for which the analog signal above or below a ramp signal, and the histogram block generates the time-correlated histograms of values using the determined time intervals. Furthermore, in some implementations, the analog-to-digital converters receive the analog signals from photodiodes, such as photo diodes used in Light Detection and Ranging (LIDAR) devices. In some such applications, the use of time intervals to generate time-correlated histograms may be used to reduce the effects of time jitter.
