EC GATE 2020 Q47: MOS Small-Signal Norton Equivalent Resistance

```

EC > GATE 2020 > Small-Signal Analysis

Using the incremental low frequency small-signal model of the MOS device, the Norton equivalent resistance of the following circuit is

r_ds+R+g_mr_dsR

(r_ds+R)/(1+g_mr_ds)

r_ds+1/g_m+R

r_ds+R

Correct : b
