Multistandard-compliant receiver architecture with low-voltage implementation

Multistandard-compliant wireless transceivers with low-voltage low-power implementation are in great demand to match the proliferation of multiple WLANs and the continuous scaling of CMOS technologies. This paper proposes both the architecture and the corresponding circuit techniques to implement a low-IF/zero-IF reconfigurable receiver IF-to-baseband chip for IEEE 802.11a/b/g WLAN. Optimum low-voltage circuit techniques enabled a successful operation at 1 V in 0.35-μm CMOS.
