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.

Transcribed Image Text: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 represents the current drawn by a portion of a digital circuit 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.

**Figure 5: Linear Model of the Microprocessor**
The diagram is labeled "Linear Model of a Digital Microprocessor" and depicts a series circuit with a power supply voltage \( V \) and three resistors: \( R_1 \), \( R_2 \), and \( R_3 \). Between the resistors, there are three current sources: \( I_1 \), \( I_2 \), and \( I_3 \). Voltage drops across each resistor are indicated as \( V_1 \), \( V_2 \), and \( V_3 \), respectively. The direction of current flow is shown with arrows.
