A1. (a) Explain why frequency compensation may need to be applied to an operational amplifier when negative feedback is applied. [10 marks] (b) A particular operational amplifier has an open-loop gain of 100 dB and poles in its uncompensated frequency response at 100 kHz, 1 MHz and 10 MHz. (i) Determine the value of (frequency independent) B and the corresponding closed-loop gain for which there will be a phase margin of 45° (ii) Sketch a Bode diagram to illustrate the design a of dominant pole frequency compensation arrangement to allow a closed-loop gain of 20 dB with a 45° phase margin. What is the bandwidth of the amplifier produced? [15 marks] [Total 25 Marks]
