Conversion of Hybrid Parameters in Transistor Three Configurations

Conversion of Hybrid Parameters in Transistor Three Configurations: Some transistor manufacturers provide only the four CE hybrid parameters while others provide CB hybrid parameters. Sometimes, for a specific purpose, it becomes necessary to convert one set of h parameters in one configuration to another set in another configuration. The conversion formulas can be obtained using …

Variations of Hybrid Parameters of a Transistor

Variations of Hybrid Parameters of a Transistor: The variation of h parameters depends upon junction temperature, collector current and collector-to-emitter voltage VCE. Among these factors, the variations of Hybrid Parameters of a Transistor due to junction temperature and collector current are significant and thus discussed here. Variation of h Parameters Due to Temperature Variation: From …

Determination of h Parameters from Static Characteristics

Determination of h Parameters from Static Characteristics: Functional relationships for the CE configuration of total instantaneous collector current and base voltage in terms of two variables (base current and collector voltage) are given from earlier equations respectively. Such functional relationships are represented by families of characteristic curves of transistors, already described. Two families of curves …
