Consider the basic diff-amp with active load and current biasing in Figure 13.14. Using the parameters and results of Example 13.8, determine the maximum range of common-mode input voltage under the conditions that the minimum source-to-drain voltage for a PMOS is limited to \(v_{S D}(\mathrm{~min})=v_{S D}(\mathrm{sat})+0.2 \mathrm{~V}\) and the minimum drain-to-source voltage for an NMOS is limited to \(v_{D S}(\mathrm{~min})=v_{D S}(\mathrm{sat})+0.2 \mathrm{~V}\).
