The circuit of Fig. P2.50 is similar to that of Fig. 2.50, except that the inclusion of R2 increases the current through R1, thus raising VCE and expanding the collector’s downswing capability when the circuit is used as an amplifi er. (a) Assuming VCC 5 5 V, VBE(on) 5 0.7 V, F 5 100, and VA 5 `, specify standard 5% resistance values to bias the BJT at IC 5 2 mA and VCE 5 2 V under the constraint that I R2 5 I B. What is the resulting value of VCE? (b) Find the range of variability of IC and VCE if 50 # F # 200.
