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.

Claim (Index 1):
A wideband RF amplifier comprising:\n a distributed amplifier comprising plurality of first gain stages, wherein each of the first gain stages comprises a first and a second transistor connected in cascode between an input transmission line and an output transmission line, wherein gate of the first transistor is connected to the input transmission line and source of the first transistor is grounded and drain of the first transistor is connected to the second transistor with an intermediate inductor, and wherein gate of the second transistor is connected to an input filter and drain of the second transistor is connected to the output transmission line; and a buffer amplifier cascaded with the distributed amplifier, wherein the buffer amplifier comprises a plurality of second gain stages connected in parallel, and wherein each of the second gain stages comprises a pair of a third and a fourth transistor connected in cascode with an intermediate inductor, wherein the buffer amplifier incorporates one or more resonant networks and wherein the one or more resonant networks are designed to provide a positive gain slope at higher frequencies.
