Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

I need some help solving this: I found the measured resistance to be R1=980, R2=982 and R3=490. I need to use these values to calculate the reference current and the output current of the widlar current source. I know the formula for the reference current is: (V-Vbe)/R1 Im not sure what the formula for output current is nor how to solve for it. How would I go about solving this and is my reference current formula correct?
Answer: + There are two questions, first about an ideal diode and then about a modeled diode. For the modeled diode, the voltage across its terminals is 0.7V when it is "on". Which of the following statements are true about the ideal diode above? a. It is possible for i to be positive. b. If i= 0, then v ≤ 0. c. If i > 0, then the diode can be replaced by an independent current source. d. If v = 0, then the diode can be replaced by an independent current source. e.

A diode is a two-terminal, electronic device made using semiconductors that is designed to prevent current from flowing in a particular direction. The symbol is a triangle pointing in the direction that (positive) current is allowed to flow and a wall preventing (positive) current from flowing in the opposite direction: 1: A diode has two modes, "on" and "off". When "on", current flows, and when "off", no current flows. We generally view diodes as either "ideal" or "modeled", as described below. "Ideal" view of a diode + The "ideal" diode is either a short circuit or an open circuit. Specifically, when the voltage across its terminals is negative, no current flows, and when current flows, there is zero voltage across its terminals, as pictured below: Diode "Modeled" view of a diode +51 Diode V Ideal Diode "Off" i=0| + U≤0 + I Therefore, with current i and voltage v defined as shown on the left above, for an "ideal" diode: • Current i cannot be negative.

Question in the photo attached please
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.
