Abstract
Techniques for facilitating analog-to-digital converter calibrations are provided. In one example, a method includes, for each of a plurality of time instances, generating a first ramp signal started at the time instance relative to a respective start of a first counter signal and generating a respective comparator output signal based on the first ramp signal and a first threshold signal. The method further includes capturing a respective first value of the first ramp signal in response to a transition of the respective comparator output signal. The method further includes determining a respective second counter value of a second counter signal based on the respective first value. The method further includes determining a scaling factor based on the second counter values and the time instances. Each of the first values is associated with the same counter value of the first counter signal. Related devices and systems are also provided.
