Four-terminal analysis of the Hall generator

The four-terminal parameters of the Hall generator are derived and then used to develop expressions for input impedance, output impedance, current gain, and voltage gain. The theoretically determined expressions are then verified for a Hall generator using indium antimonide. The four-terminal equations are given as a function of conductivity, Hall constant, temperature, magnetic field, and dimensions of the material. Thus, the designer may use these expressions in the application of Hall-effect devices.
