Two low-power, high-gain preamplifiers designed for a 7.2-7.7GHz (high band) FM-UWB receiver in 0.25mum SiGe:C-BiCMOS technology are described. Each preamplifier has single-ended input/differential outputs and is aimed at low-power, low data rate applications. Both amplifiers consume 3.6mW from a 1.8V supply. The maximum measured voltage gain is Gt30dB with 500MHz bandwidth for both designs, and they...
