In the design of electronic amplifier circuits, every active device has biasing to set its operating point, the steady state current and voltage on the device when no signal is applied. In bipolar transistor biasing, for example, a network of resistors is used to apply a small amount of DC to the base terminal of the transistor. The AC signal is applied at the same terminal and is amplified. The bias network is designed to preserve the applied AC signal. Similarly, amplifiers using field-effec… WebJan 24, 2024 · The inductor should also be rated to handle the load current and its DC resistance (DCR) must be low enough so that the load current does not generate a …
