Design of broadband bandpass cascaded singlestage distributed amplifier in 0.13 #x03BC;m CMOS technology for UWB applications

摘要

This paper presents a broadband bandpass amplifier in CMOS technology based on the cascaded single-stage distributed amplifier (CSSDA) technique. In this design, the conventional lowpass LC filter structure of the CMOS CSSDA is replaced by a bandpass LC filter structure lines. The CSSDA has a nearly constant gain, linear phase response, and acceptable return loss in the passband. Simulation results clearly indicate that the proposed circuit topology can be used as a broadband bandpass amplifier for UWB applications.
