Abstract

This paper presents the design of a power amplifier for full-band UWB application systems using a CMOS 0..18um technology. A wideband RLC filter and a multilevel RLC matching scheme are utilized to achieve the wideband input/output matching. Both the cascade and cascode stage are used to increase the gain and to achieve gain flatness. Simulation results show that the designed amplifier provides a power gain greater than 10 dB throughout the UWB full-band(3.1-10.6GHz) and an input P1dB of -1.2dBm at 6.9GHz. It consumes 35.8mW from a 1.8V supply.
