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 was designed and fabricated in a 180nm CMOS process and it requires a supply voltage of 1.8V, with a die area of 0.01mm2. A train of Gaussian Monocycle Pulses (GMP), modulated by a random data sequence of 1Gb/s, has been detected successfully by the detector. Ability to process differential data without using conventional blocks like mixer, correlator etc. while consuming a very low power (3.8pJ/bit for a data rate of 1Gb/s) is the novelty of this work. The detection scheme employing a simple architecture with a noncoherent detection mechanism is well suited for UWB-IR communication system.
