A long-channel $NMOS$ transistor is biased in the linear region with $V_{DS}=50$ $m$ $V$ and is used as a resistance. Which one of the following statement is $NOT$ correct?
- If the device width $W$ is increased, the resistance decreases.
- If the threshold voltage is reduced, the resistance decreases.
- If the device length $L$ is increased, the resistance increases.
- If $V_{GS}$ is incresed, the resistance increases.
