Question:

The transistor circuit in Figure P7.76 is a Darlington pair configuration. Using a computer simulation, determine the upper \(3 \mathrm{~dB}\) frequency and the midband voltage gain for

(a) \(R_{E 1}=10 \mathrm{k} \Omega\),

(b) \(R_{E 1}=40 \mathrm{k} \Omega\), and

(c) \(R_{E 1}=\infty\). Use standard transistors. Explain any differences between the results of the three parts.
