Analogue to digital convertor architecture with a signal leveldetector

A new signal level detector for a flash-type A/D convertor is introduced. It operates like a comparator with the 1-of-n encoder of flash-type A/D convertors. Because the clock signal can be omitted in the application of the comparator, clock feedthrough noise is not a problem. A resolution of up to 8 bits in A/D conversion is feasible
