Consider the common-base circuit in Figure P7.42. Choose appropriate transistor parameters.

(a) Using a computer analysis, generate the Bode plot of the voltage gain magnitude from a very low frequency to the midband frequency range. At what frequency is the voltage gain magnitude \(3 \mathrm{~dB}\) below the maximum value? What is the slope of the curve at very low frequencies?

(b) Using the PSpice analysis, determine the voltage gain magnitude, input resistance \(R_{i}\), and output resistance \(R_{o}\) at midband.
