Analysis of UWB pulse generator for short range applications

Abstract

This paper presents the design of ultra wideband (UWB) pulse generators, and the performance metrics are analyzed. Two configurations of pulse generators for UWB transmit only system is presented for short range applications. These pulse generators are designed to cope with the requirements of the low power IEEE 802.15 standard wireless body area network (WBAN) technology. It uses a short pulse width of UWB pulses to achieve low power consumption without multipath fading and interference. It provides interoperability with other narrowband technologies. The first configuration consists of tunable pulse generator, which consumes power of about 5.4 μW. In the next configuration, the resistive sensing pulse generator controls the voltage in a voltage control ring oscillator (VCRO), and it consumes power of 0.15 μW, at a frequency of 45 MHZ. The simulation results obtained show that the performances of these UWB pulse generators satisfies the required FCC constraints.
