 The M atrix Amplifier is a structure designed to increase the gain of the wideband distributed amplifiers.  A promising method for the deployment of high-speed optical systems with completely integrated transceivers by utilizing CM OSdistributed amplifiers with bandwidths of gigahertz to a few tens of gigahertz  The stable gain and excellent terminal match across a wide frequency range are the key reasons for the increased usage of distributed amplifiers.  The solution to the gain bandwidth roll-off problem is in this paper.  Decreasing the roll-off problem in which the values of the gain and BW are approximately balanced (High gain and high bandwidth).The M atrix Amplifier is a structure designed to increase the gain of the wideband distributed amplifiers. A matrix amplifier is used to improve the pass-band gain while preserving the dispersed design-wide characteristics to use the multiplicative gain mechanism. In this paper, the matrix distributed amplifier methodology is developed using differential cells instead of active amplifier cells to improve the wideband characteristics. Shunt capacitances are connected in the centerline to absorb the peaking impact at a cut-off frequency and reduce gain ripples. As an application of the ideas and concepts of matrix amplifiers, a modified step -by-step design of rows 4 and column 2 matrix amplifier is undertaken using a Quasi Differential amplifier. A M atrix differential amplifier using a shifted-second-tier structure technique is then built and tested in 0.18 µm Complementary M etal Oxide Semiconductors technology. The advantages gained from the proposed design are high gain, high bandwidth, low noise, and no need for balun circuits.The design and simulation results were achieved using ADS. The significant results show a high gain of 40 dB and a 33 GHz bandwidth. The noise figure is also 3.583, with S11, S22, and S12 being -10 dB, -10dB, and -40dB, respectively; the output power at 1-dB gain compression point is evaluated (P1dB) of +6.4 dBm, and the total DC power dissipation is 266mW. The cadence tools produced the layout design and specifications, although the chip size was 1.1mm 2 .

“…With the benefit of the reverse phase path constructed from the distributed amplifier, the isolation of the proposed quasi-circulator can be accomplished by phase cancelation. The practical FET's dimension and circuit parameters can be optimized for excellent performance with the aid of criterion (18), an iterative electromagnetic simulation and TSMC kit. In the practical design, the characteristic impedance Z c of the artificial transmission line for the distributed balun and the phase cancelation path has different values.…”

This paper presents the implementation of a broadband quasi-circulator through a cascading distributed balun using a 90-nm CMOS process. The isolation, |S31|, of the proposed three-port quasi-circulator can be acquired through the phase cancelation technique, by connecting an additional distributed amplifier in parallel between ports 1 and 3. The thorough analysis based on an eight-port chain matrix and scattering matrix is presented for refining the circuit parameters in the initial design. Measured results show that the proposed quasi-circulator attains a broad operation bandwidth ranging from 10 to 67 GHz. Moreover, the quasi-circulator also has good insertion gain of 0.5 to 4.8 dB, as well as isolation |S31|, which is better than 23 dB. Consequently, the proposed quasicirculator delivers wide bandwidth performance, good port-toport isolations, good insertion gain, and high linearity based on the cascading distributed balun with phase cancelation technique.

“…Actually, a large number of broadband amplifiers with a non-zero common-mode amplification has been reported in the literatures [1][2][3][4][5] and they require an additional balun to drive differential mode antennas. Many solutions have been already proposed in the literatures [6][7][8][9][10][11][12][13][14][15][16][17][18][19], both as passive or active architectures, but all of them experiment some drawbacks for the considered application. Typically, a balun composed of passive components has a large size (in the order of several square centimetres), and usually has a relatively narrow bandwidth.…”

In this study, the authors present a 36:1 relative bandwidth active front‐end low‐noise amplifier (LNA) with power limiter that has been developed for airborne ultra‐wideband receiver systems. The proposed system is driven by an external antenna with a balanced mode with an input impedance of 150 Ω. The whole microwave monolithic integrated circuit (MMIC) embeds a protection from the presence of high‐level signals, an ultra‐wideband amplifier circuit, an active balun and an impedance transformer. It has a bandwidth ranging from 0.5 to 18.0 GHz with 14 dB gain, 4.5 dB noise figure (NF), 20 dB common‐mode rejection and 30 dBm input overload protection. The circuit has a single bias from the output port greatly simplifying its use within a receiving system and can be directly integrated into the antenna mechanical support. Test measurements are also provided.
