Design of Broadband Bandpass Matrix Amplifier in 0.13- CMOS Technology for UWB Communication Systems

This paper presents a novel broadband bandpass amplifier in CMOS technology based on the matrix amplifier technique. In this design, the conventional lowpass LC filter structure of the CMOS matrix amplifiers is replaced by a bandpass LC filter structure in input and output lines. The matrix amplifier has a nearly constant gain, linear phase response, and acceptable return losses in the passband. Simulation results clearly indicate that the proposed circuit topology can be used as a broadband bandpass amplifier for UWB applications.
