MI Review Consider the circuits shown in (Figure 1). (Figure 2), (Figure 3), (Figure 4), (Figure 5). Assume that the op amp is ideal. Each of the circuits has negative feedback, so the summing point constraint applies. Suppose that R1 = 6 kN and R2 = 5 kN. Part A For the circuit shown in (Figure 1) find the value of vo. Express your answer to three significant figures and include the appropriate units. v. = Value Units Figure Figure...

(a) State the properties of an ideal opamp. Give one reason why
the assumption that an opamp is ideal is useful when calculating
the behaviour of circuits containing opamps? [3]
(b) Figure Q3 shows the circuit diagram of an amplifier
constructed using an ideal opamp. State the value of the voltage v–
appearing at the inverting input of the opamp. Clearly state what
properties of an ideal opamp you are assuming. [2]
(c) Hence calculate the currents flowing through the...
Problem 2 4.7 k22 #/ Find the output voltage of the op amp in the circuit at right. For the NMOS, VIn = 1 V and Kn = 0.5 mA/V2. The op amp is ideal. + Suggestion: As always, write down what you know and follow the rules. It's not that hard. 1 k92 Vs = -5 V vo
Problem 4) The circuit shown in Figure P4 has been in operation for a long time. At t 0, the source voltage suddenly jumps to 250 V. Find the voltage and current of the capacitor for t>0. 8 kN 160 mH S0 V 10 nF () Figure P4
Learning Goal: To use the node-voltage method to solve circuits that contain resistors and independent sources. The node-voltage method is a general technique for solving circuits. Fundamentally, it involves writing KCL equations at essential nodes. You should review KCL and the definition of an essential node before beginning. In this tutorial, you will use the node-voltage method to find the current through the voltage source, io , and the voltage drop across the 5 kN resistor, vo, for the circuit...
