WebIt is required to design a BJT amplifier that meets all of the listed below specifications. The designed amplifier must be AC-coupled for the load and the signal source, but the coupling between its intermediate stages may be of AC or DC type, as per the designer’s choice. There are no restrictions in terms of using NPN or PNP transistors. WebAmplifier class operation is categorized with alphabetical letters: A, B, C, and AB. For Class A operation, the entire input waveform is faithfully reproduced. Amplifier Class Class A Operation can only be obtained when the transistor spends its entire time in the active mode, never reaching either cutoff or saturation.
