A inductorless non-coherent IR-UWB CMOS receiver for 3–5GHz band applications

In this work, an IR-UWB RF Receiver compliant with 802.15.3a standard is fabricated on a single chip using 0.18um CMOS technology. The Receiver chip covers 3-5GHz lower band and 3-stage LNA is realized without on-chip inductor, which reduces the chip size dramatically down to 1.8mmx 0.9mm. The input signal is differential type in order to improve the immunity from common mode noise and undesired harmonic noise caused by detector and comparator circuit. The sensitivity of receiver is -70dBm at data rate of 5Mbps in condition of BER 10"3. The actual test shows that the UWB communication is properly operated up to 8m distance. The consumed power is 24mW, which is very useful for low power sensor network.
