In the circuit of Fig. P2.22 let VS 5 5 V, R1 5 20 kV and R2 5 3.0 kV. Moreover, let the BJT have F 5 150, VBE(on) 5 0.7 V, VCE(EOS) 5 0.2 V, VCE(sat) 5 0.1 V, and VBE(sat) 5 0.8 V. (a) Find the range of values for R3 for which the BJT will operate in the FA region, and calculate the BJT’s terminal currents. (b) Find the BJT’s beta if R3 is raised to twice the value that causes the BJT to operate at the EOS. (c) What is the value of if R3 is removed from the circuit and the collector terminal is left fl oating?
