Question:

The Hall effect experimental arrangement was described in Example 11.4. The required diff-amp is to be designed in the circuit configuration in Figure P11.35. The transistor parameters are $V_{T N}=0.8 \mathrm{~V}, k_{n}^{\prime}=80 \mu \mathrm{A} / \mathrm{V}^{2}$, $\lambda_{1}=\lambda_{2}=0$, and $\lambda_{3}=\lambda_{4}=0.01 \mathrm{~V}^{-1}$. If the CMRR requirement cannot be met, a more sophisticated current source may have to be designed.
