BJT Biasing Articles: DC Load Line of BJT Biasing Circuit: The DC Load Line of BJT Biasing Circuit is a straight line drawn on the transistor output characteristics. For a…
Bipolar Junction Transistors Articles: Transistor Operation: pnp and npn Transistor Operation – A junction transistor is simply a sandwich of one type of semiconductor material (p-type or n-type) between two…
Complementary MOSFET Common Source Power Amplifier: Advantages of MOSFETs: Complementary MOSFET Common Source Power Amplifier have several advantages over power BJTs for large signal amplifier applications. One of the most…
BJT Power Amplifier with Differential Input Stages: Amplifier Circuit - The direct-coupled amplifier in Fig. 18-33 has a BJT Power Amplifier with Differential Input Stages constituted by transistors Q1 and…
Power Supply Decoupling: Power Supply Decoupling - High-power amplifiers require high supply current levels, so unregulated power supplies are often employed to avoid the power wasted in a series regulator.…
Output Current Limiting: Because the output transistors can be destroyed by excessive current flow, output current limiting circuits are often included in a power amplifier. Figure 18-27 shows the typical…
Quasi Complementary Output Stage: The Quasi Complementary Output Stage was originally developed because complementary high-power transistors were not readily available. Despite the fact that such transistors are now available, the…
