Transistorized Voltage Regulator (Zener & Transistor)

Transistorized Voltage Regulator (Zener & Transistor)

Transistorized Voltage Regulator Why use a transistorized voltage regulator? If we use a half or a full-wave rectifier we can convert an AC voltage in a DC one. This converted voltage is unregulated, because the output voltage is not constant and can change due to variations of the load value. To reduce these variations we connect […]

Ebers Moll Model of a Bipolar Transistor

Ebers Moll Model of a Bipolar Transistor

The bipolar transistor is an electronic device that originates a big evolution in the electronics field. The basic features of the bipolar transistor are introduced on this topic. We’ll study the basic model (Ebers Moll Model) of these devices and their use in the analysis of circuits biasing.

Circuit for measuring beta of transistor

Circuit for measuring beta of transistor

Determining the beta of a transistor (β) with a voltage-current converter and current-voltage converter.

The beta (β) is a characteristic of each transistor. This feature is found in the NTE, ECG manuals, etc. These manuals have a minimum or approximate values of the real values. This means that we do not know the real value of the transistor.
