Suggest one way of sizing the transistors of the logic

Click For Summary
SUMMARY

The discussion focuses on the sizing of transistors in a logic circuit to achieve a worst-case tpHL equal to that of an inverter with a minimum (W/L) ratio. The participant calculated a worst-case ratio of 3 but expressed uncertainty regarding the theoretical approach to suggest a sizing method. The conversation highlights the need for a clear understanding of transistor sizing principles and their impact on propagation delay in digital circuits.

PREREQUISITES
  • Understanding of transistor sizing principles in digital logic design
  • Familiarity with propagation delay metrics, specifically tpHL
  • Knowledge of inverter characteristics and (W/L) ratios

Homework Statement


Suggest one way of sizing the transistors of the logic circuit such that its worst case
tpHL equals the tpHL of an inverter with a sizing of (W/L)min.

Homework Equations


I think the only equation is the (W/L) itself.

The Attempt at a Solution


I have actually done the front part of the question and I got the worst case ratio to be 3. But I am not too sure about the theory part to suggest a way. Anyone help?
 
Physics news on Phys.org
anyone?
 
I probably can't help with the question, but I wonder how you got "3" without any numbers given in the problem statement.
