Design a bipolar cascode amplifier with a cascode active load similar to that in Figure P10.89 except the amplifying transistors are to be pnp and the load transistors are to be npn. Bias the circuit at \(V^{+}=10 \mathrm{~V}\) and incorporate a reference current of \(I_{\mathrm{REF}}=200 \mu \mathrm{A}\). If all transistors are matched with \(\beta=100\) and \(V_{A}=60 \mathrm{~V}\), determine the small-signal voltage gain.
