Technologies/Materials of Transistors and Amplifiers a Coplanar Amplifier at High Frequencies
Summary:
In this thesis, the integrated circuits that are used as amplifiers are studied in terms of fabrication (technology and materials) and design issues. Initially, the different types of substrates and metal strip of the transmission lines are presented for the propagation of millimetric electromagnetic waves, co-planar technology as well as microstrip line. In addition, the types of transistors are analyzed according to their behavior and structure, as well as their function as voltage signal amplifiers. Additionally, the design parameters of low noise amplifiers and power amplifiers are presented, utilizing the advantages of feedback. Furthermore, the structural characteristics of the transistors, as well as the fabrication materials of the waveguide transmission lines are studied. With transmission lines, optimum signal performance is achieved at the circuit input and output by adjusting the circuit’s resistance to the characteristic resistances of the low noise amplifier industry. The parameters of the stability, noise and unilateral factors for the development of the integrated amplifier are studied, where different instances of input and output adaptation are being put into testing. Conclusions are made on the optimal transmission line, according to construction materials on the basis of the relative dielectric constant coefficients, at the lowest possible cost. Finally, small as well as large signal models and low noise amplifier topologies with feedback are studied based on different parameters and noise factors. Conclusions are made after designing a circuit in ADS in terms of a functional amplifier design.
