Question

What is the equivalent hybrid parameter for the transistor hybrid parameter hoe?

(a) h11

(b) h12

(c) h21

(d) h22

This question was posed to me by my college director while I was bunking the class.

Enquiry is from Conversion Formulas for the Parameters of the Three-Transistor Configurations in portion Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

Right option is (d) h22

For explanation I would say: The transistor hybrid parameter hoe is equivalent to the hybrid parameter h22. The transistor hybrid parameter is a measure of the input open circuit with output admittance. The transistor equivalent parameter is a ratio of the current across one terminal and the voltage.
