    Abstract: In this paper, a mathematical analysis of a Small-Signal Single-Stage Transistor Amplifier using Hybrid Parameter and the development of a software to aid this analysis was carried out. This was borne out of the desire to be able to correctly and accurately analysis small signal transistors to get the required performance quantities that can be use... Show More

    Abstract: The work characterizes the electric dipole moment and the infrared spectrum of the molecule C13H20BeLi2SeSi. Calculations obtained in the ab initio RHF (Restrict Hartree-Fock) method, on the set of basis used indicate that the simulated molecule C13H20BeLi2SeSi features the structure polar-apolar-polar predominant. The set of basis used that have a... Show More
