,System Simulation of Δ-Σ-Based Fractional-N Synthesizers, WLAN standards (802.11a, b, and g). In chapter 3, detailed analyses of integer-N and Δ-Σ-based fractional-N phase-locked loops have been presented. Open-loop, closed loop, and phase noise equations have been derived. In this chapter, behavioral modeling for a proposed fractional-N Δ-Σ-based PLL is

In this chapter, unconditionally stable Δ-Σ modulators of the third order (namely MASH-1-1-1) are implemented and employed in a phase-locked loop fractional-N synthesizer providing a go

However, additional circuit could be designed to enhance the performance of the synthesizer at the cost of increased circuit complexity. Those additions include adaptive CP architecture to maintain loop gain and phase transfer functions while operating in

Gain and noise contributions of individual subblocks of the synthesizers are detailed. Loop filter design is also included. Together with simulations performed in chapter 4, the derived equations aid the optimum des
