Cascadable flash analog-digital converters.

摘要

An analogue to digital converter for converting an analogue input signal which lies within an analogue input range, comprises a stack of comparator circuits (12, 42) each corresponding to a subrange of said analogue input range, wherein said converter (10, 40) is operable to provide a digital output signal defining the subrange containing said analogue input signal (Vin), and an analogue output signal or signals defining the position of said analogue input signal within said subrange, said analogue output signal or signals being derived from the inputs to said comparator circuits (12, 42). <IMAGE>
