1. A method, comprising: applying analog-to-digital conversion, in a signal processing component, to an analog input via a plurality of successive conversion cycles, wherein each conversion cycle corresponds to a particular bit in a corresponding digital output; for each one of the plurality of successive conversion cycles, triggering a next one of the plurality of successive conversion cycles based on a cycle termination event; detecting meta-stability during each one of the plurality of successive conversion cycles; retaining information relating to result of said detecting of meta-stability during each conversion cycle until end of the analog-to-digital conversion; after completing all of the plurality of successive conversion cycles, assessing a meta-stability state based on retained information for results of all of the plurality of successive conversion cycles; and controlling the digital output based on the assessing.
