Abstract

This paper presents a matrix-based lumped-element theoretical analysis of CMOS distributed amplifiers that employ the image impedance technique for the input/output terminating networks. The design of distributed amplifiers can be more efficient in CMOS technology by using lumped-element modelling of the distributed amplifiers rather than the one commonly based on transmission line parameters. The simulation results clearly indicate an improved voltage gain and a better gain uniformity over the bandwidth of the proposed amplifier design. Moreover, this matrix-based lumped-element method is suitable for analysis of any distributed amplifier with an arbitrary terminating network.
