Abstract:
The present disclosure relates to an integrated wideband Radio Frequency (RF) amplifier, based on a complementary metal oxide semiconductor (CMOS) technology. In an embodiment the amplifier addresses the shortcomings of conventional wideband amplifiers and is based on a distributed amplifier (DA) topology which typically exhibit severe performance degradation when externally loaded with parasitic circuit elements. In an embodiment of the present invention a buffer amplifier at the output of a conventional DA is able to compensate the impact of parasitic elements. The disclosed circuit can be implemented by fabricating the wideband RF amplifier integrated circuit (IC) on a 130 nm CMOS technology or other comparable CMOS technologies.
