This paper presents a digital baseband design for passive sensor and identification systems using asymmetric wireless links with ultra wideband (UWB) radio. As opposed to traditional wireless sensor and identification systems using halfduplex communication in narrowband frequency, impulse-LTWB is applied as an uplink in the proposed system. A novel baseband protocol is devised to improve the system efficiency in the multitag environment while maintaining the power constraint. By utilizing adaptive slotted ALOHA anti-collision algorithm, 1000 tags can be processed within 5OOms. The contributions also include the development of a low-power digital baseband processor for passive tags. The simulation is successful and the FPGA prototype is operational. The chip is implemented for ASIC and it Kill be fabricated and tested Kith the front-end in IP6M UMC 0. 18 mu m process.
