Abstract
A low-power multiresolution spectrum-sensing (LP-MRSS) IC utilizing self-deactivated partial swing techniques is fabricated in 0.18-μm complementary metaloxideCMOS technology. The LP-MRSS is composed of a low-power digital window generator, analog correlators, low-power pipeline analog-to-digital converters, and a fast-sweeping frequency synthesizer. The LP-MRSS dissipates 122 mW at a 1.8-V supply voltage achieving an approximately 33% power reduction over the previous MRSS IC.
