7.106 Consider the single-supply bias network shown in Fig. 7.52(a). Provide a design using a 9-V supply in which the supply voltage is equally split between RC, VCE, and RE with a collector current of 0.6 mA. The transistor β is specified to have a minimum value of 90. Use a voltage-divider current of IE /10, or slightly higher. Since a reasonable design should operate for the best transistors for which β is very high, do your initial design with β =∞. Then choose suitable 5% resistors (see Appendix J), making the choice in a way that will result in a V BB that is slightly higher than the ideal value. Specify the values you have chosen for RE, RC, R1, and R 2. Now, find VB, VE, VC, and IC for your final design using β =90.
