摘要: GaInP/GaAs HBT inductorless wideband amplifiers using shunt-series shunt-shunt dual-feedback topology (Kukielka topology) and shunt-series series-shunt dual-feedback topology (Meyer topology) are demonstrated in this article. Three amounts of feedback are applied on each topology. At the high-gain mode, the Kukielka/Meyer wideband amplifier achieves the small-signal power gain of 30127 dB with the 3-dB bandwidth of 6 GHz at a 5 V supply. The noise figure of both amplifiers is lower than 3 dB within 6 GHz. To increase the amount of feedback widens the bandwidth at the cost of power gain and noise figure degradation.
