An amplifier with a dc gain of 60 dB has a single-pole, high-frequency response with a 3-dB frequency of 100 kHz.

(a) Give an expression for the gain function A(s).

(b) Sketch Bode diagrams for the gain magnitude and phase.

(d) What is the unity-gain frequency?

(e) If a change in the amplifier circuit causes its transfer function to acquire another pole at 1 MHz, sketch the resulting gain magnitude and specify the unity-gain frequency. Note that this is an example of an amplifier with a unity-gain bandwidth that is different from its gain-bandwidth product.
