Design a discrete transistor feedback current amplifier to provide a current gain of 30. Assume the available transistors have parameters \(h_{F E}=120\) and \(V_{A}=\infty\). The signal current source has a source resistance of \(R_{S}=25 \mathrm{k} \Omega\) and the load is \(R_{L}=500 \Omega\). Verify the design with a computer simulation. Determine \(R_{i f}\) and \(R_{o f}\).
