Question:

Design an emitter-follower circuit with the configuration shown in Figure 6.49 such that the input resistance $R_{i}$, as defined in Figure 6.51, is $120 \mathrm{k} \Omega$. Assume transistor parameters of $\beta=120$ and $V_{A}=\infty$. Let $V_{C C}=5 \mathrm{~V}$ and $R_{E}=2 \mathrm{k} \Omega$. Find new values of $R_{1}$ and $R_{2}$. The $Q$-point should be approximately in the center of the load line.
