4.6. Graphical Perspective of Output Characteristics and the Load Line
The transistor output characteristics from Unit 3 and the variable increments along with their linear relationships are illustrated in Fig. 4.7. This would be applicable, for example, to the amplifier of Fig. 2.4. (As in that circuit, no body effect is included.) The circuit is biased with drain – source voltage VDS and drain current ID. A positive signal Vg is applied to the gate terminal. In response, there appears drain signal voltage –Vd, due to the rise in drain current. Signal voltages are with respect to the source or ground.
