Question:

Consider the common-base circuit in Figure 7.33 in the text. The transistor parameters are \(\beta=90, V_{E B}(\mathrm{on})=0.7 \mathrm{~V}\), and \(V_{A}=\infty\). A load capacitance of \(C_{L}=3 \mathrm{pF}\) is connected in parallel with \(R_{L}\).

(a) Determine the midband voltage gain.

(b) Determine the upper \(3 \mathrm{~dB}\) frequency.
