In this paper, analysis, simulation and design of a distributed amplifier (DA) with 0.13µm CMOS technology in the frequency range of 3-40 GHz is presented. Gain cell is a current reused circuit which is optimum in gain, noise figure, bandwidth and also power dissipation. To improve the noise performance in the frequency range of interest, a T-matching low pass filter LC network which is utilize...

In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...

A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....

This paper presents a four-stage CMOS distributed amplifier (DA) design implemented in standard 0.18 μm CMOS technology. The proposed design eliminates the need for transmission line capacitors and, consequently, uses significantly smaller spiral inductors compared with the previous designs. Using the minimum size inductor, the bandwidth of the amplifiers is extended, and the quality factors of...
