A 800 Mb/s CMOS detection scheme for UWB impulse-radio communication

A CMOS detection procedure for ultra-wideband impulse radio (UWB-IR) communication system, employing Bi-Phase Shift Keying (BPSK) modulation scheme, is presented here. The chip, designed and fabricated in a 0.18 μm CMOS process, requires a supply voltage of 1.8 V and occupies a die area of 0.01 mm2. A train of Gaussian monocycle pulses (GMP), modulated by a random data sequence of 800 Mb/s, is detected successfully by the detector. The detection scheme employing a very simple architecture with a power consumption of 3 mW is well suited for non-coherent wireless communication system.
