Chapter 4, Problem D4.86DP

A source−follower amplifier with the configuration shown in Figure 4.31 is to be designed. The power supplies are to be ± 12 V. The transistor parameters are $V_{TN}=1.2\text{V}$ , ${k^{\prime }}_n=100\mu {\text{A/V}}^{\text{2}}$ , and $\lambda =0$ . The load resistance is $R_L=200\text{k}\Omega$ . Design the circuit, as well as a constant−current source, to de liver 250 mW of signal power to the load.
