Abstract :
A successive-approximation quantization technique in a flash-like architecture is presented. Beside its simple hardware requirements, if allows direct cascading of identical stages without subtracting amplifiers or D/A converters. Speed losses as well as the decision cost per bit are therefore greatly reduced. Due to its modular architecture and low power requirements it is amenable for monolithic fabrication. The technique is useable for several high-resolution high-speed applications such as HDTV, Computer-Aided Tomography, and ultrasound scanning
