Recent developments in Wireless technology has led to proliferation of various personal area networks which demand for high speed data transmission at low power imposing stringent requirements on the building blocks of such network nodes. The advancement in CMOS process technology due to scaling has led to digital circuits gaining more advantage than the Analog counterpart. The task of building precision Analog circuits in deep sub-micrometer CMOS technology has become challenging both in-terms of achieving high Dynamic range and Low Power. Hence the current trend is to digitize the signal as early as possible by moving Analog to Digital interface circuitry closer to the Antenna so that most of the processing is done in Digital domain. Digitizing right at the antenna implies higher dynamic range requirements which inturn implies higher power. This has led to digitizing the signals at Intermediate Frequency rather than processing the Base-band signal so that the final down conversion can be done precisely in digital domain. In this Project we have implemented a Second order Continuous time Sigma-delt
