In this paper, a low-power single-phase clock multiband flexible divider for Bluetooth, Zigbee, and IEEE 802.15.4 and 802.11 a/b/g WLAN frequency synthesizers is proposed based on pulse-swallow topology and is implemented using a 0.18μm CMOS technology. The multiband divider consists of a proposed wideband multimodulus 32/33/47/48 prescaler and an improved bit-cell for swallow(s) counter and operates in 2.4 to 5GHz resolution selectable from 1 to 25MHz. However, the designers do have a few methods which they can use to reduce this static power consumption.
