Q. 4.SP.1

If C_S = 0 and all else is unchanged in Example 4.2, find the extremes between which v_S swings.


Verified Solution

Voltage v_{gs} will swing along the dc load line of Fig 4-6(b) (which is now identical to the ac load line) from point a to point b, giving, as extremes of i_D,  3.1  \text{mA} and 0.4  \text{mA}.    The corresponding extremes of v_S = i_DR_S are 6.2  \text{V} and 0.8  \text{V}.
