The nominal \(Q\)-point of the circuit in Figure P5.67 is \(I_{C Q}=1 \mathrm{~mA}\) and \(V_{C E Q}=5 \mathrm{~V}\), for \(\beta=60\). The current gain of the transistor is in the range \(45 \leq \beta \leq 75\). Design a bias-stable circuit such that \(I_{C Q}\) does not vary by more than 5 percent from its nominal value.
