Question

21. Compare the data sheets for the uA741 and TL081 op-amps (as attached overleaf) and highlight and discuss the differences in terms of rise time, slew rate and bandwidth. (a) (8 marks) (b) Design an inverting op-amp circuit with a gain of -100 and calculate the bandwidth each of the different op-amps would give you (6 marks) Using only uA741s design a circuit, if possible, to provide the same (c) performance in terms of gain and bandwidth as the TL081 circuit in (b) (6 marks)

Please help
