Abstract
Power amplifier is an important component in the wireless communication system. Design of the power amplifier in UWB transceiver is challenging as the signal need to be transmitted over a wide bandwidth. Several criteria need to be fulfilled such as good linearity, good wideband matching, high efficiency and low power consumption.This paper presents the design of a power amplifier with 3.1-10.6 GHz using 0.18 μm CMOS technology for ultra-wide band application. The proposed power amplifier used three cascaded amplifier stages in order to achieve good gain and wide-band width. The results show that the proposed power amplifier design hasan average gain of 7.28 dB, an input return loss less than -7.48 dB, an output return loss less than -4.782 dB, and group delay variation of ±151.9 ps is achieved over the entire band. A good input1dB-compression point of 6.67 dBm and input third order intercept point of 0 dBm is achieved at 5 GHz.
