  1. Multi-Standard Radio University of Tehran Faculty of Electrical and Computer Engineering ASIC Design Course – Spring 85 – Instructor: S. M. Fakhraei ClassSeminar: Mohammad Reza Ghaderi Karkani mrghaderi@ece.ut.ac.ir Most of materials are borrowed from ISSCC 2006 proceeding CD

  2. Outlines • Introduction • Radio Hardware Platform • Recent works • GSM/GPRS • GPS for Cell-phones • DVB-H • MB-OFDM UWB • GSM/802.11g WLAN • Conclusion

  3. Introduction • Reconfigurable devices for combined signal paths are technology enablers for Multi band, Multi mode, Software Radio and Multi standard Radios. • Features for future multiradio devices: • Cellular: GSM/WCDMA/… • Wireless broadband: WLAN 802.11a/b/g/n/… • Short range connectivity: BT & UWB • Positioning: GPS/Galileo • Broadcast/TV: DVB-H • Design considerations: • Architecture and system partitioning • Power management • IP blocks and interfaces

  4. From Factor of Multimedia WCDMA/GSM GPS/GALILEO BT/WLAN DVB-H UWB WLAN diversity WCDMA diversity

  5. Radio Hardware Platform • How many ASIC’s? • Single-chip radios or separate RF & BB ASIC’s • External RF components: antennas, filters, PA’s, switches,… • How many modules? • Antennas distributed all over the product • Increased ASIC integration level not any more the only driver in system architectural partitioning • Options • Separate single-chip ASIC’s or system modules close to antenna • One centralized modem with distributed antennas • Something in between (including different choices)

  6. A Fully Integrated SoC for GSM/GPRS in 0.13µm [2] Infineon

  7. A Fully Integrated SoC for GSM/GPRS in 0.13µm [2]

  8. A Fully Integrated SoC for GSM/GPRS in 0.13µm • Crosstalk from the digital blocks into RF is one of the biggest concerns in single-chip transceivers. • Substrate noise pickup, package crosstalk, magnetic coupling between the coils, and supply coupling degrade the RF performance. [2]

  9. A 20mW 3.24mm2 Fully Integrated GPS Radio for Cell-Phones • Cellular phones with embedded GPS engines will enable network-based positioning methods. • Assisted GPS solutions allow a direct migration path into 3G handsets besides being more accurate than cell tower-based ones. [3] RFDomus

  10. DVB-H • DVB-H is a new standard that is expected to be widely deployed in future mobile devices. • The first DVB-H field trials were held in Europe and used the UHF band. • DVB-H has also been targeted for deployment in the United States using L-band spectrum between 1670MHz and 1675MHz. • There has also been discussion of reallocating European L-band DAB frequencies for DVB-H service.

  11. Dual-band Single-Ended-Input Direct-Conversion DVB-H Receiver [4] Microtune, Plano

  12. A Multi-Band Multi-Mode CMOSDirect-Conversion DVB-H Tuner [5] Samsung

  13. Measured performance summary comparison Dual-band Single-Ended-Input Direct-Conversion DVB-H Receiver► [4] ◄A Multi-Band Multi-Mode CMOSDirect-Conversion DVB-H Tuner (0.18μm 40GHz-fT CMOS technology) [5]

  14. A 1.1V 3.1-to-9.5GHz MB-OFDMUWB Transceiver in 90nm CMOS [6] NEC

  15. A 1.1V 3.1-to-9.5GHz MB-OFDMUWB Transceiver in 90nm CMOS [6]

  16. Software-Defined Radio Receiver • A software-defined radio (SDR) can tune to any frequency band, select any reasonable channel bandwidth, and detect any known modulation. • While progress has been made on DSP and baseband functions for SDR, the low-power radio front-end has remained elusive. • An ADC at the antenna which digitizes all bands simultaneously with equal fidelity will not be practical in the foreseeable future. • Today’s mobile SDR receiver needs a wideband, linear RF front-end that can be tuned to any one channel at a time in the band from 800MHz to5GHz.

  17. An 800MHz to 5GHz Software-Defined Radio Receiver in 90nm CMOS [7] UCLA

  18. An 800MHz to 5GHz Software-Defined Radio Receiver in 90nm CMOS • The on-chip receiver selectivity at 900MHz is sufficient for GSM and at 2.4GHz for 802.11g WLAN [7]

  19. Conclusion • Multi-Standard Radio Design is not only an ASIC level issue • Hierarchical design and design abstraction are needed in system design • Hybrid solutions cover numerous different options to realize Multi-Standard Radio
