1. Refer to the following common-base amplifier. The transistor has a \( \beta \) of 200 ; and the amplifier is in the active mode. By adjusting the value of \( R_{2} \) the input resistance of the amplifier, \( R_{i n} \), can be adjusted accordingly. If \( R_{\text {in }}=30 \Omega \) is required, what would be the new value for \( R_{2} \) ? (40 points)
