In this paper, we present a novel passive CMOS module which uses two different standards in uplink and downlink. It can be used in many applications such as Radio Frequency Identification (RFID), and ubiquitous wireless sensing. Such as conventional RFID systems, the module captures power supply from received RF signal transmitted by a reader and extracts data and clock by using an envelope detector and PIE encoder. However, in uplink instead of back scattering, an Impulse-UWB transmitter is used to improve the system performance and throughput. The UWB communication offers several advantages to the system. A new communication protocol is proposed for the system based on slotted-ALOHA anti-collision algorithm. The module consisting of a power management unit, an RF narrowband receiver, a clock management unit, an IR-UWB transmitter, and a digital baseband are designed in 0.18 CMOS process.
