We present the design of two wide-band, low-power and low-noise amplifiers (LNAs) using SiGe BiCMOS technology. The distributed LNA demonstrated 0.1-23-GHz bandwidth and 14.5-dB gain with less than ±1-dB gain flatness. It exhibited 5-dB noise figure and 14.8-dBm output IP3, and dissipated 54-mW dc power. Comparable circuit performance was also obtained in the lumped LNA while utilizing only one-fifth the chip area of the distributed LNA.
