For a NMOS transistor sized and biased with a fixed , how much does the unity-gain frequency of the transistor, , change with a 5% decrease in and a 10% decrease in ?

 An NMOS triode device is biased with a fixed . Size the device so that it has a small signal resistance of or less under statistical variations.
