	SiGe BiCMOS RF Circuit Design: A Wideband LNA Example
	M. Sperling ABSTRACT:
	A wideband amplifier with 15 dB gain and a 3-dB bandwidth of 2.8 GHz implemented in an advanced SiGe bipolar technology is presented. The noise figure is less than 4.4 dB while dissipating only 16 mW from a 2.5-V supply. The resulting figure of merit Gain / (Power * Noise Figure) of 0.213 exceeds those of recently published SiGe and RFCMOS wideband designs. The architecture chosen is a noise-canceling topology with shunt resistive feedback for wideband matching to 50 Ohms. Finally, the importance of modeling test bed parasitics is emphasized in the context of RF circuit design.
