The gain of the transistor will be listed in the datasheet as either ?DC or H the needed base current required to turn on the transistor. Looking at the
The h-parameters of a transistor will give you a good idea of how to use it effectively in a circuit, and whether it is appropriate for a particular circuit.
for the measurement of transistor and integrated circuit (I C) parameters over the frequency range 10 kHz to 100 MHz, The h parameters if II and V2 are
The above equations define the h-parameters of the transistor in CE configuration.The same theory can be extended to transistors in other configurations.
Also this type of bipolar transistor configuration has a high ratio of output parameters and therefore the current gain of the transistor can be given as:
Module-2 Contents BJT as amplifier. Small signal equivalent circuits -h parameter model.Transistor Biasing circuits. Stability factors. Thermal runaway.
A transistor has low input impedance and high output impedance and hence the use of Z and Y As a result the hybrid of 'h' parameters
Analysis of Small-signal ansistrT or Amplifi ers Thus, knowing the values for a transistor 's h-parameters, the prediction
Transistor Models • Review of Transistor Fundamentals • Many, many models of transistor action. • h-parameter and hybrid-pi model are similar,
What is the reason for using h-parameters when describing transistors? Why are they used instead of the physical description?
