Consider the simplified op-amp shown in Figure 14.11. Use standard transistors and take the output at the collector of \(Q_{6}\). Assume the bias current for \(Q_{1}\) and \(Q_{2}\) is \(I_{Q}=19 \mu \mathrm{A}\) and the bias current for \(Q_{5}\) and \(Q_{6}\) is \(I_{Q}=0.15 \mathrm{~mA}\). Let \(C_{1}=30 \mathrm{pF}\).

(a) Using a computer simulation, determine the slew rate of the amplifier.

(b) Using a computer simulation, determine the small-signal bandwidth for (i) \(v_{d}=1 \mu \mathrm{V}\) and (ii) \(v_{d}=5 \mu \mathrm{V}\). Use an appropriate load.
