In the circuit below, the transistor exhibits a saturation current of $I_s = 1$ pA, common-emitter current gain of $eta = 85$, and an Early voltage of $V_A = 15$ V at $T = 300$ K: 5 V 1.1 k$Omega$ 100 k$Omega$ $I_C$ $V_{BE}$ a) Assume that the transistor is operating in the forward-active mode and determine the DC operating point of the transistor ($V_{BE}$, $I_C$). Ans: $V_{BE} = 568.433$ mV; $I_C = 3.767$ mA b) Verify your assumption that the transistor is operating in the forward-active mode. Ans: $V_{CE}$ > $V_{BE}$; forward-active mode is correct.

Assume that an npn bipolar transistor has a common-emitter current gain of $\beta=100 .(a)$ Sketch the ideal current-voltage characteristics $\left(i_{C}\right.$ versus $\left.v_{C R}\right)$, like those in Figure $12.9$, as $i_{B}$ varies from zero to $0.1 \mathrm{~mA}$ in $0.01-\mathrm{mA}$ increments. Let $\nu_{C E}$ vary over the range $0 \leq \nu_{C E} \leq 10 \mathrm{~V} .(b)$ Assuming $V_{c c}=10 \mathrm{~V}$ and $R_{c}=1 \mathrm{k} \Omega$ in the circuit in Figure $12.8$, superimpose the load line on the transistor characteristics in part $(a) .(c)$ Plot, on the resulting graph, the value of $i_{c}$ and $\nu_{C E}$ corresponding to $i_{6}=0.05 \mathrm{~mA}$
