Abstract

The Ultra-Wideband (UWB) system has emerged as a major solution for wireless communication due to its wide bandwidth and high data rate. As the deployment of UWB gathers pace, consumer electronic devices, PC peripherals and mobile devices manufacturers are striving to develop their first cost effective system-on-a-chip (SOC) transceiver. In this work, the design and implementation of the three main building blocks in a radio frequency (RF) transceiver, namely power amplifier (PA), low noise amplifier (LNA) and mixers that fully complies with the compulsory band for UWB MB-OFDM (3.168 to 4.752 GHz) specifications are presented. Employing 0.18 µm RF CMOS technology, the proposed LNA, PA and mixer are systematically analyzed, simulated, fabricated and measured. The proposed single-stage LNA is based on two transistors cascode topology. Source inductive degeneration and interstage inductor are employed to increase the overall broadband gain while maintaining a low noise figure. The proposed PA uses two-stage common source (CS) architecture, also with inductive degeneration. Finally, an inductorless mixer using the conventional single-balanced topology with active baluns is implemented, using low and high-side LO injections.
