Integrated ultra-wideband receiver system and antenna design

Abstract

Ultra wideband (UWB) is one of the important technologies among the communication types, which is able to reach high data rate in short distances. Wireless personal area networks and wireless sensor networks are the primary of the application areas of this technology. The aim of this thesis is to design a receiver integrated circuit (IC) which is able to work at high data rates, by using UWB technology. The transmitter IC working in collaboration with the receiver IC, is designed by the other members of the project group. The required literature survey is done in order to have a receiver IC to work properly. As an architecture, energy detection type non-coherent impulse radio UWB system is selected because of its relatively smaller complexity. In circuit design phase, the circuit topologies that have proper results in the literature, are determined and among all these topologies, the low noise amplifier (LNA), integrator and comparator circuits are designed with the simulation programs. The layouts of the designed circuits are drawn with UMC's 130 nm complementary metal oxide semiconductor (CMOS) technology for the manufacturing. Moreover, for the measurement purpose of the previously designed IC, a printed circuit board is designed. A research on microstrip line structures is done in order to comply with the properties of the receiver IC and also the theoretical data is supported by the simulation results. As a conclusion, an UWB antenna which maintains the communication between transmitter and the receiver, is designed.
