In summary, the conversation discusses the number of transistors needed for a circuit being taught by the professor. The speaker counted and found that there are 22 transistors, but there may be 2 more needed for a Q' output. They suggest asking the professor for clarification, but mention that they missed her class and will have to contact her through email. The possibility of adding an inverter to isolate the load is also mentioned. The conversation ends with the speaker expressing concern about the professor questioning their absence from class.

Our professor is teaching this circuit and she mentioned there are 24 transistors. But I counted and it comes out to be 22
T1 to T4 needs 2 (transistor) * 4 = 8 transistors
Each inverter needs 2 transistors. so 7 inverters need 14 transistors.
total 22 transistors.
Unless we're also creating a Q' in the output, so that'll need 2 more transistors. But that's not mentioned in the circuit.

Why don't you ask her, showing your calculations?

Because I missed her class and I saw this in her video lecture. And she is in another campus. Her lectures are conducted online.

You can always try an email :smile:

Then she'll ask me why I missed her class, and I was at the gym at that time.

I think that is probably the answer. We'll always be needing complementary outputs. There is a Q’ available in the internals, but loading that point may upset internal switching/timing performance. An additional inverter will isolate the load.

Would she not believe that you re-read your notes and only thought of the question later?
Or do you feel too guilty? :wink:
