Article Title: A CMOS Impulse Radio Ultra-Wideband Transceiver for Inter/Intra-chip Wireless Interconnection
by Nhan Nguyen, Nghia Duong, Anh Dinh

This paper presents a CMOS impulse radio ultra-wideband (IR-UWB) transceiver designed and implemented using IBM 0.13um CMOS technology for inter-chip and intra-chip wireless interconnec-tion. The IR-UWB transmitter is based on the high order derivative Gaussian pulse using LC-Tank oscillator. A pulse for the 6.3-10GHz IR-UWB transmitter generated with low power, high peak amplitude, and high frequency. This pulse PSD fully complies with the FCC spectrum mask. The IR-UWB receiver is based on the non-coherent architecture which removes the complexity of RF architecture (such as DLL or PLL) and reduces power consumption. The receiver consists of three blocks: a low noise amplifier (LNA) with active balun, a correlator, and a comparator. Simulation results of the IR-UWB transmitter show a pulse width of 1.1ns, a peak to peak amplitude pulse of 90mV and an energy consumption of 39pJ/pulse at 200MHz pulse repetition rate (PRR). The receiver provides a power gain (S21) of 12.5dB, a noise figure (NF) of 3.05dB, an input return loss (S11) of less than -16.5dB, a conversion gain of 18dB, a NFDSB of 22, and a third order intercept point (IIP3) of -1.3dBm. The transceiver uses an area of 0.38mm2 and consumes 30.7mW of power on the 1.4V power supply. The results show a promising transceiver for wireless communications applicable to 3-D ICs due to its low complexity and small chip area.
