本文设计了一款0.13μm CMOS功率放大器，具有超宽瞬时带宽，适用于UWB高分辨率成像系统。该PA能够传输任意瞬时UWB波形，满足FCC规定的峰值EIRP限制，解决了集成CMOS UWB成像收发机中线性放大器的需求。
The increased interest in Ultra-WideBand (UWB) impulse-based systems for high-resolution imaging applications [1] has created a demand for mediumpower linear amplifiers capable of transmitting such signals (FCC limits peak EIRP to 18dBm for UWB signals with 3GHz bandwidth). An integrated CMOS power amplifier (PA) with the ability to transmit arbitrary instantaneous UWB waveforms has significant value in realizing a completely-integrated silicon UWB imaging transceiver. UWB radar and imaging systems that utilize waveforms occupying the FCC-allocated lower GHz frequency bands (960 to 3100MHz) are attractive for wireless search-and-rescue and see-through-thewall sensing applications as well as within-the-wall imaging due to the lower electromagnetic attenuation of most materials at these frequencies. The main contribution of this paper is the realization of an integrated 0.13µm CMOS power amplifier that is suitable for signals with an ultra-wide instantaneous
