Question

In a triode, $\mu, g_{m}$ and $r_{p}$ are related as

• A. $\mu=r_{p} \times g_{m}$
• B. $g_{m}=r_{p} \times\mu$
• C. $\mu=\frac{r_{p}}{g_{m}}$
• D. $r_{p}=\mu\times g_{m}$

Answer 1

Answer: (A)

$\mu=r_{p} \times g_{m}$

Answer 2

In a triode, the relation between $\mu, r_{p}$ and $g_{m}$ $\mu=\left(\frac{\Delta V_{p}}{\Delta V_{g}}\right)_{\Delta l_p}$ is constant $=\frac{\Delta V_{p}}{\Delta I_{p}} \times\frac{\Delta I_{p}}{\Delta V_{s}}$ $\mu=r_{p}\times g_{m}$
