Abstract [en]

In this paper, we present a self-powered CMOS impulse-based ultra wideband radio system for RFIDs and Wireless sensor networks (WSN) applications. It is integrated in a Liquid-Crystal Polymer (LCP) based System on Package (SoP) module with an embedded small antenna. Our contribution includes using two different standards in up and downstream link. In downstream link, due to demand of low complex, low cost and low power circuit, a very simple and extremely low power pulse width demodulator is used to extract the data from received RF signal. An IR-UWB transmitter is used to transmit the data in upstream link. Power supply is taken from the received RF electromagnetic wave with help of a Schottky diode voltage multiplier. Unlike traditional wireless systems, due to great advantages of UWB communication this Transponder does not suffer from multipath fading, collision problem and multi-user interference. The front-end circuit consists of the power converter; PWM receiver, IR-UWB transmitter, and embedded UWB antenna are designed for integration on Liquid-Crystal Polymer (LCP) substrate.
