Design and Implementation of Amplifier Circuit Based on EWB Environment

Abstract

This study details the creation and execution of a common-emitter amplifier circuit utilizing the 2N2222 NPN transistor. The study explores the fundamental principles of amplifier circuits and highlights key parameters such as voltage gain, current gain, and input/output impedance. Through simulations conducted on the EWB platform, the designed amplifier circuit demonstrated significant voltage gain and phase inversion, confirming the expected characteristics of the common-emitter configuration. The results indicate that the amplifier operates effectively within a wide frequency range, showing good bandwidth and stability. This design approach can serve as a foundation for further exploration and optimization in amplifier circuit design, particularly in modern electronic devices.
