Abstract

The analysis of voltage series multistage feedback amplifier network is achieved by evaluating the nodal admittance matrix of the equivalent circuit representing the replacing of each transistor in a stage by its high frequency small-signal model and the performing of the high order voltage transfer function of the system. The main reasons of treating such a wide-band amplifier network are of its stabilized voltage gain and its ability to amplify the pulses occurring in a television signal. The frequency response of the system is calculated and confirmed. System dynamics and variation of input signal are obtained by calculating the response of a continuous time system. The discrete-time equivalent to the analogue system allows the system designer to choose an appropriate pulse transfer function to investigate the performance of the system suitable for a given specifications and requirements. The software powerful MAT-LAB version 7.2 techniques is used for treating the single expression transfer function obtained by assigning numerical values and the response of the system in time and frequency domain.
