A high-speed A/D converter architecture for high-resolution applications

Two high-speed A/D converter architectures are described. They make use of the hardware simplicity of cascaded and cyclic converter architecture. They could directly be cascaded to provide high resolution at reasonable component count. To attain enough speed reserve for cascading, the flash converter architecture is used as their core. Its relative hardware simplicity makes if amenable for monolithic integration. A 14-bit design example that could be used for several high speed applications is given.
