+ | ===== Problem Statement ===== | ||
+ | * Design of a 1V supply, 14-Bit, High-Speed Continuous-time Sigma-Delta Modulator in UMC90nm process. | ||
+ | * Achieve high Figure of Merit for the given design problem. | ||
+ | * Try adding Mash Architecture ( to support higher input signal Bandwidth by reducing OSR) | ||
+ | * Input Signal to be assumed as a wide-band signal. ie. significant level of out-of-band signals present | ||
