Question:

The simple MOSFET amplifier with active load shown in Figure 10.33 is biased at $V^{+}=3 \mathrm{~V}$. The reference current is $I_{\mathrm{REF}}=80 \mu \mathrm{A}$. The transistor parameters are $V_{T N}=0.5 \mathrm{~V}, V_{T P}=-0.5 \mathrm{~V}, K_{n}=K_{p}=0.1 \mathrm{~mA}$, and $\lambda_{n}=\lambda_{p}=0.02 \mathrm{~V}^{-1}$.

(a) Find $V_{S G}$.

(b) What value of $V_{I}$ will produce $V_{D S O}=V_{S D 2}$ ?

(c) Determine the small-signal voltage gain.
