We present a dual-band, dual-mode shared hardware approach for backscatter based data uplinks. This all-digital approach yields a custom 900 MHz 6.25 Mbps differential quadrature phase-shift-keying ...

A truly-monolithic 900-MHz CMOS wireless receiver with on-chip RF and IF filters and a fully-integrated fractional-N synthesizer is presented. Implemented in standard 0.5-/spl mu/m CMOS process and ...
