Q. 3.3
Apply SPICE methods to determine the CE transfer characteristics for the generic npn transistor (QNPNG).
Step-by-Step
Verified Solution
Figure 3-6(a) presents the connection method chosen for determination of the transfer characteristics. The associated netlist code follows:
| Ex3_3.CIR Vbe 1 0 0V Q 2 1 0 QNPNG Vc 2 0 1V .MODEL QNPNG NPN(Is=10fA Ikf=150mA Isc=10fA Bf=150 + Br=3 Rb=1ohm Rc=1ohm Va=30V Cjc=10pF Cje=15pF) .DC Vbe 0V 2V 0.01V Vc 0V 2V 0.2V .PROBE .END |
Execution of 〈Ex3_3.CIR〉 and use of the Probe feature of PSpice yields the desired transfer characteristics displayed by Fig. 3-6(b).
