Abstract

A fully integrated CMOS ultra‐wideband (UWB) transmitter module is proposed for UWB applications. The transmitter module consists of a band‐notched UWB antenna and a transmitter IC which integrates a pulse generator, a gating signal generator and driver amplifiers (DAs). The drive amplifier uses a two‐stage amplifier—a Class‐E amplifier and a Class‐A amplifier with switch control, to significantly reduce power consumption (522 μW/20 Mbps). Fabricated using a 0.18‐μm CMOS process, the generated pulse then passes through the DA, which not only drives the antenna but also shapes the generated digital signal to meet the Federal Communications Commission spectral mask specification. © 2009 Wiley Periodicals, Inc.
