This paper presents a low power glitch-free dual-modulus (15/16) prescaler based on the phase-switching for Ultra-Wide Band (UWB) transceiver. An inherently glitch-free phase-switching prescaler is realized by the adoption of a reverse switching sequence without any additional complicated circuit. A simplified model of the source coupled logic (SCL) structure is proposed to optimize the power of the...
This paper presents the attractive features and challenges of developing multi gigabit persecond wireless connectivity by UWB technology. Low complexity and low power UWB transceivers' architecture in both lower 6 GHz UWB band and 60 GHz millimeter wave band are implemented. Chipset development is successfully demonstrated in both 6 -GHz UWB transceiver IC in 0.18 μm CMOS and 60-GHz MODEM in 90 nm...
This paper presents an integrated 4 GHz divide-by-16/17 dual-modulus prescaler (DMP) with enhanced input sensitivity over extended operation range for ultra-wide band (UWB) transceiver. By modeling the n-stage differential CML D flip-flop ring oscillator based injection-locked frequency divider (ILFD), tradeoffs associated with input sensitivity, locking range and the sizes of the transistors have...
