Abstract


As Technology progress deeper into submicron CMOS, traditional analog circuits face problems that are not to be solved purely by analog innovations. Instead, new architectures are being proposed which take advantages of the relatively cheaper of the digital circuits to augment or improve the diminishing performance of the analog circuitry. The conventional approach performs the design of 14 bands CMOS frequency synthesizers with spur reduction for MB-OFMD for analog circuits which have high distortions and noise. My proposed work is to replace the analog input PLL into All Digital PLL with spur reduction. Then the frequency mixing architecture alleviates harmonics mixing and pulling to diminish spur generation. The simulation is performed using Model SIM and the implementation using Microwind to diminish spur reduction.
