Abstract: In this paper an efficient multiband flexible divider for Bluetooth, Zigbee and other wireless standards is proposed based on pulse swallow topology and is implemented using Xilinx ISE 9.1i and modalism SE10.0b.It consist of a propose wideband multimodulus 32/33/47/48 prescaler, swallow s-counter ,p-counter. As a modification I have implemented a modified multiband flexible divider by replacing norgate by pass transistor in a wideband single phase prescalar clock 2/3 prescaler. Compared to the proposed system modified one will reduce the area,circuit complexity, power consumption,transistor counts .
