Hybrid pi model Wikipedia. The full model introduces the virtual terminal, B', so that the base spreading resistance, rbb, (the bulk resistance between the base contact and the active region of the base under the emitter) and rb'e (representing the base current required to make up for recombination of minority carriers in the base region) can be represented separately.This is the limit imposed by the problem. It results in a max. permissible Vs per the given formula ("ruling condition") of 13.9 mV. This is a poor circuit in that it results in massive harmonic distortion if the input Vs isn't kept to a small value. Reason is lack of negative feedback due to infinite R_E bypass capacitor.1.

The hybrid model is a combination of one or more techniques that is used to form one single workflow. It is advantageous for the organization as it helps to carry out the operation and process in better form compared to other models. The standards of the process can be maintained by using the hybrid model in the organization.
