A 3.1–10.6 GHz Ultra Wide-band Impulse Radio Transmitter with Notch Implementation for In-Band Interferers in 90nm CMOS Conference Paper uri icon

abstract

  • One of the serious challenges in Ultra Wide-band (UWB) systems is the in-band interferer system in the middle of the UWB band which affects the system performance severely. In this paper an analog in-band interference avoidance IR-UWB transmitter is presented. The fully integrated transmitter generates a novel UWB pulse with a tunable notch at the frequency of 802.11a interferer. The pulse covers the whole UWB spectrum (3.1-10.6 GHz) which makes it suitable for high resolution high data-rate applications. The transmitter has a bi-phase modulation and has been fabricated in IBM 90nm CMOS. © 2012 IEEE.
