Design of broadband bandpass CMOS amplifiers based on modified distributed amplification technique

This paper presents a novel broadband bandpass amplifier in CMOS technology based on the distributed amplification technique. In this design, the conventional lowpass LC filter structure of the CMOS distributed amplifiers is replaced by a bandpass LC filter structure only in gate transmission lines. The drain transmission lines topology is preserved to provide a DC path for biasing the transistors. Simulation results clearly indicate that the proposed circuit topology can be used as a broadband bandpass amplifier for UWB applications
