Tiss article provides a detailed ep -by-step guide to designing a BJT-based audio ampliers, including necessary calculations. It cover the selection of providents, biasing, and performance analysis to ensure the assampfier meets desired specifies.
Understanding the Basic Configuration
Ez a közös-emitter amplfier egy popular configuration, avagy audio amplication due to its high gain. Te tervezz proces begins with defining the requid voltage gain, input impedance, and output impedance.
Choosing the Transistor and Biasing
A BJT, a such a the 2N3904 or BC547, a based on prepart and voltage ratings. Biasing consures the transistor operates in the active regionon for linear amplication. The bias point, or Q- point, it set by choosing investor prepart (I 1; 1d; FLT: 0 3dd; 3d; 1d; 1d); 3nd); 3nd).
