Question:

Figure P16.79 shows two CMOS inverters in cascade. This circuit can be thought of as an uncoupled CMOS R/S flip flop. The transistor parameters are $K_{n}=K_{p}=0.2 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=0.5 \mathrm{~V}, V_{T P}=-0.4 \mathrm{~V}$, and $\lambda_{n}=\lambda_{p}=0$. Plot $v_{O 1}$ and $v_{O}$ versus $v_{I}$. In particular, calculate the values of $v_{O 1}$ and $v_{O}$ at $v_{I}=1.5,1.6,1.7$, and $1.8 \mathrm{~V}$.
