By Adem Aktas,Mohammed Ismail

CMOS PLLs and VCOs for 4G Wireless is the 1st e-book dedicated to the topic of CMOS PLL and VCO layout for destiny broadband 4th iteration instant units. those units may be handheld-centric, requiring very low energy intake and small footprint. they are going to be in a position to paintings throughout a number of bands and a number of criteria protecting WWAN (GSM,WCDMA) ,WLAN(802.11 a/b/g) and WPAN(Bluetooth) with assorted modulations, channel bandwidths , section noise specifications ,etc. As such, this publication discusses layout, modeling and optimization concepts for low strength totally built-in broadband PLLs and VCOs in deep submicron CMOS.
First, the PLL and VCO performances are studied within the context of the selected multi-band multi-standard, radio structure and the followed frequency plan. subsequent an intensive examine of the layout specifications for broadband PLL/VCO layout is performed including modeling innovations for noise resources in a PLL and VCO concentrating on optimization of built-in section noise for multi-carrier OFDM 64-QAM sort functions. layout examples for multi-standard 802.111a/b/g in addition to for GSM/WCDMA are totally defined and experimental effects from 0.18 micron CMOS try chips have established the validity of the proposed layout and optimization strategies. both vital the paintings describes strategies for strong excessive quantity creation of RF radios as a rule and for built-in PLL/VCO layout particularly together with concerns resembling provide sensitivity, floor leap and calibration mechanisms.
CMOS PLLS and VCOs for 4G Wireless can be of curiosity to graduate scholars in electric and desktop engineering, layout managers and RFIC designers in instant semiconductor companies.
