“…However, the sensitivity of the UWB receiver can be degraded by interference signals from other wireless communication systems. The major interferer sources are the in-band signals from IEEE 802.11a WLAN systems and the out-band signals from IEEE 802.11b/g WLAN systems, which occupy the frequency bands of 5-6 GHz and 2.4-2.48 GHz, respectively [1,2,3]. These interferers cause distortions in the UWB RF receiver circuits, such as gain compression, crossmodulation distortion, and intermodulation distortion.…”

A CMOS 3-5 GHz ultra-wideband (UWB) low-noise amplifier (LNA) with an integrated active interferer rejection is presented. The LNA eliminates the out-band 2.4 GHz interferers without deteriorating the input matching and gain by employing the active tunable bandpass feedback loop to produce a notch at the interferer frequencies. The proposed LNA is fabricated using a 0.18 µm CMOS process. The 3-5 GHz UWB LNA with the integrated bandpass feedback loop achieves an out-band 2.4 GHz interferer rejection of 29.2 dB, a power gain of 15.3 dB, and a minimum noise figure of 4 dB with a power consumption of 9.1 mW.

A multichannel transceiver design with low hardware complexity, flexibility and efficient spectrum use intended for Impulse Radio (IR) Ultra-Wideband (UWB) apertures, is proposed in this paper. The transceiver supports 14 channels and is implemented in TSMC CMOS process. The transmitter adopts a symmetrical triangular narrow pulse generator, a multiband LC-VCO, a mixer and a Variable-Gain Amplifier. A digital control of transmitter output power and carrier frequency is achieved by a current-steering Digital-to-Analog Converter (CS-DAC). The receiver follows the noncoherent Energy Detection (ED) scheme including Low-Noise Amplifier (LNA) which takes the benefits of the body biasing technique to further reduce power consumption, squarer and comparator. The LNA achieves high gain of up to 30[Formula: see text]dB allowing to enhance the receiver sensitivity which is [Formula: see text]83.7[Formula: see text]dBm at 25[Formula: see text]Mbps. The transmitter provides output pulses with a width of 3[Formula: see text]ns, a pulse repetition rate of 20[Formula: see text]ns and a maximum Power Spectral Density (PSD) of [Formula: see text]42[Formula: see text]dBm/MHz. The power consumptions of transmitter and receiver are 35.6[Formula: see text]pJ/bit and 0.207[Formula: see text]nJ/bit at 25[Formula: see text]Mbps, respectively. Maximizing utilization of the scarce wireless spectrum, enhancing spectral flexibility and efficiency and reducing power consumption are the main contributions brought by this work, enabling this transceiver to be able to deal with the current debate on producing single multifunctional Cognitive Radio (CR) UWB systems.
