## Homework Statement

Determine transistor sizes for

*(lets say a 2 input nand gate, my actual question is more complicated but i want to know the basic idea so i can do it myself)*so that the worst case pull down and pull up is equivalent to a single inverter with Wn = 1 micro m and Wp= 2 Micro m

All transistor lengths are 0.25 micro meters

## Homework Equations

Basic Mosfet knowledge should do i guess.

## The Attempt at a Solution

i know the solutions, i just dont know how to arrive at it.

My guess was that the equivalent transistor W/L for the PDN or PUN should be the same as the W/L for the PDN or PUN of the inverter. But the numbers dont add up.
