Low power, 20 Mbit/s, Ultra-Wide Band Transceiver Integrated Circuit Suitable for Communicating Objects Radio Interface

The purpose of this paper is to present a radio frequency Impulse Radio Ultra-Wide Band (IR-UWB) communication method and integrated circuit (IC). The simple hardware architecture, the low power consumption and the relatively high achievable data rate make this system well adapted for use in portable, battery powered communication objects. The transceiver uses a Frequency Hopping On-Off Keying modulation (FH-OOK) with a non-coherent demodulation. A single chip transmitter/receiver was designed in a CMOS 0.13μm process. The chip includes the radio frequency part and the base-band signal processing circuits. The maximum data rate is 20Mbit/s at a distance of 5m (without an error correction convolutional code). The power consumption is 20mW.
