Briefly explain your understanding of what an op-amp is, including how it operates. (b) Do a research of 741 op-amp, then state two manufacturer vendors of it and their popular applications. Read the specification, explain what is the open-loop amplifier and close-loop amplifier in your own words and find what the maximum voltage can supply to the op-amp. (c) Circuit shown in Figure 1 contains an op-amp, resistor R1 and R2 as one of its elements. Student will select the value of resistor in Table 1 regarding their group number. • Compute the closed-loop gain v0/vs. • Find the current i if vs = 3V. (d) Construct the circuit of question (c) in LTspice. Measure the gain and find the current i by the simulation in LTspice. Note that the op-amp needs ± 12V DC power supply and you can use LT1001 op-amps model. (e) Consider applying the 2V peak-to-peak sinewave and frequency 1KHz to the input (vs) of op-amp, plot the output v0 and explain the reason why you get that result.
