Electrical Engineering Question oblem 2-1-1 L POINTS 1 Consider the schematic of an op amp shown below. Select all the statements that are true. Vo V. O Adding a feedback connection from the output terminal to the negative input terminal increases the operating range of the op amp ithat is, the range of input values for which the op amp does not saturate) O For an ideal op amp, , =0 O For an ideal op amp, i = i, -0. I For an ideal op amp, =0 An op amp is an active device that requires an external power supply to farvtion An op amp is made fronminea eleents

2) The circuit shown below uses a diode in the feedback path of the op amp. For each question, use only the ideal switch model to analyze the circuit's behavior (i.e. ignore the diode's 0.7V forward drop). Assume that R = 1k2, and the op amp is ideal. D VOUT VIN a) Suppose vIN=2V. What direction is the current i passing through R? Is the dio ON or OFF? Wha VOUT b) Suppose VIN = -2V. What direction is the current i passing through R? Is the diode ON or OFF? What is voUT? c) Explain why VOUT can never be less than 0V.

An op amp, with the parameters indicated below, is used in a feedback configu-ration as shown. If the input voltage is Vin=14.5 mV, what is Vout? A = 562 kV/V •Vofs = 22.5 mV •VR = +15 V, -15 V     Please answer in typing format solution please

One of the most common applications of the op-amp is the inverting amplifier. The output is inverted relative to the input and the amplification gain is determined by the ratio of the feedback resistor (R2) to the input resistor (R1). 1. Analytically determine the "gain" of the inverting amplifier shown in Figure 2 (not including Capacitor C1). C1 1 nF R2 10 kQ Vss R1 Vdd Vin 1 ko Vout OA1 V2 V3 TLO81 5 V -5 V V1 ^) sine 1 kHz Vss
