The range of \(\beta\) for the transistor in the circuit in Figure P5.66 is \(80 \leq \beta \leq 120\). Design a bias-stable circuit such that the nominal \(Q\)-point values are \(I_{C Q}=0.2 \mathrm{~mA}\) and \(V_{C E Q}=1.6 \mathrm{~V}\). The value of \(I_{C Q}\) must fall in the range \(0.19 \leq I_{C Q} \leq 0.21\mathrm{~mA}\). Determine \(R_{E}, R_{1}\), and \(R_{2}\).
