Often it is useful to model complex chips as simple linear equivalent models to determine the effects of the current draw and to ensure safe operation of the circuit. Consider the circuit shown in figure 5, it is a model of a digital microprocessor circuit. Each current source represent the current drawn by a portion of a digital circuits in the microprocessor. The resistors represent the power distribution network from the supply to that portion of the processor. Each current source can only have the following values: either be off i.e. 0 or have a value of I.. The reason being digital circuits when they are not performing a computation consume zero power and when operational they consume an average current (in this case I). In our model all portions consume the same current when they are operational. Power Supply V (+ Linear Model of a Digital Microprocessor V₁ V₂ V 3 ww R₁ R₂ 1₂ + R3 Figure 5: Linear Model of the microprocessor 13 (a) Given the possible values for I₁, I2 and 13, what are the maximum and minimum values that V₂ can exhibit? Express your answer in terms of V, I, R₁, R2 and R3.
