Given a depletion-type MOSFET with \(I_{D S S}=6 \mathrm{~mA}\) and \(V_{P}=-3
\mathrm{~V}\), determine the drain current at \(V_{G S}=-1,0,1\), and \(2
\mathrm{~V}\). Compare the difference in current levels between \(-1
\mathrm{~V}\) and \(0 \mathrm{~V}\) with the difference between \(1 \mathrm{~V}\)
and \(2 \mathrm{~V}\). In the positive \(V_{G S}\) region, does the drain current
increase at a significantly higher rate than for negative values? Does the
\(I_{D}\) curve become more and more vertical with increasing positive values of
\(V_{G S} ?\) Is there a linear or a nonlinear relationship between \(I_{D}\) and
\(V_{G S}\) ? Explain.
