Setting steady electric potential differences and electric currents in an electrical circuit to choose its operating point.
For a p-n junction, biasing with the p-type semiconductor at positive electric potential difference relative to the n-type semiconductor.
For a p-n junction, biasing with the p-type semiconductor at negative electric potential difference relative to the n-type semiconductor.
The steady electric potential differences and electric currents about which signals vary in an electrical circuit. A small-signal model approximates nearby behavior.
A first-order Taylor expansion of an electrical circuit's response about an operating point. It describes small changes in electric potential difference and electric current; the neglected higher-order terms limit the useful signal range.
The change of output electric current per change of input electric potential difference, evaluated at an operating point with the other terminal conditions specified. In a small-signal model, describes this contribution; transconductance has the dimensions of electrical conductance.

Biasing generally refers to the process of establishing a predetermined level of voltage or current in a specific circuit, particularly in electronic components like transistors. This is crucial because it sets the operating point of the device, ensuring it functions correctly within the desired parameters. In the context of electronics, biasing can take several forms: 1. **DC Biasing**: This is the most common form of biasing for amplifiers and transistors.
