10 Strictly Confidential  Multi Band - OFDM (IEEE a) High Bit Rate,Short Range Ad hoc high speed networks between peripherals/multimedia  Single Band (Pulsed) UWB (IEEE a) Low average transmitted power Medium/Low Bit Rate TH-UWB Short pulses User separation with TDMA Discontinous transmission with low duty cycle UWB standards DS-UWB Short Pulses User separation with CDMA High duty cycle Typical of ASIC applications

11 Strictly Confidential Pulsed UWB applications Communications Short/medium Range Communications Links Radar Ground penetrating radars Through wall radars Imaging and ranging Intelligent Sensors Telemetry Motion Detectors Intelligent Transport Systems Next generation RFIDs Other Medical Applications Indoor localization (GPS assisted)

12 Strictly Confidential on-going UWB projects.. Pulsed UWB Transmitter for Military/Professional applications Medium Bit rate Long Communication Links (>100m) Ranging/Localization in indoor/urban environments Through Wall Imaging capability to be considered Robust against jamming/detection Ultra Low power Pulsed UWB Transmitter for Intelligent Sensors applications High Bit Rate short communication links (>1Mbit/sec, 2-3m) Ultra Low power requirements TDMA techniques to share the same physical channel avoiding collisions

13 Strictly Confidential UWB TX is the right solution  Ultra low power UWB TX developed in 3.1-5GHz band  1Mbit/sec short range link (2-3meters range)  Power consumption scalable with Bit Rate exploiting duty cycle (TX On/OFF with pulse) Ultra Low power Intelligent Sensors Main Transmitter Constraints Unbalanced comm link Bit Rate (typical of sensors apps) Very Low power consumption (<400uWatt at 1Mbit/sec) High immunity to multipath due to harsh environment Automotive temperature specs

14 Strictly Confidential Ultra Low power Intelligent Sensors  90nm CMOS technology chosen for high integration with digital sections  Supported modulation ppm,BPSK as to IEEE °  High stability with temperature to avoid frequency calibration  Istantaneous power consumption 6mW  Average power consumption for 1Mbit/sec 400uW TX UWB in CMOS 90nm tech

15 Strictly Confidential UWB for military/security apps Main Transmitter Constraints Low/medium BitRate (hundreds of Kbits) High immunity to multipath Robustness against jamming Wide coverage for data communication >100m Availability of precise location information -> DATA and LOCALIZATION Pulsed TH UWB  UWB TX developed in 3.1-5GHz band: large bandwidth provide good time resolution for localization  BPSK,ppm modulation as in IEEE a  Power consumption of the transmitter is not a critical factor  Emissions are critical due to probability of being detected

16 Strictly Confidential UWB for military/security apps Design Issues CMOS 90nm technology chosen for integration with high speed logic necessary for UWB receiver Low emissions and high output power with 1V supply -> Fully Differential design Integrated output matching (no ext components) Digital calibration bits to cover process spread and operating temperature variations (-30°C,+85°C) ETSI compliant pulse against process and temperature Final TX size:0.3mm 2 1.2V,2.5V power supplies Anchor #1 Anchor #2 Anchor #3 Anchor #4

17 Strictly Confidential Further developments..  Application of UWB for localization application in indoor/urban sites for public transportations  Study of localization techniques and algorithms for localization/through wall imaging for public safety and military applications  …
