 +===== 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
