The circuit shown in Figure P5.30 is to be designed such that \(I_{C Q}=0.8 \mathrm{~mA}\) and \(V_{C E Q}=2 \mathrm{~V}\) for the case when (a) \(R_{E}=0\) and (b) \(R_{E}=1 \mathrm{k} \Omega\). Assume \(\beta=80\). (c) The transistor in Figure P5.30 is replaced with one with a value of \(\beta=120\). Using the results of parts (a) and (b), determine the \(Q\)-point values \(I_{C Q}\) and \(V_{C E Q}\). Which design shows the smallest change in \(Q\)-point values?
