Relationship Between Gain and Bandwidth in Amplifiers

1- Sketch the dc transfer characteristic of the circuit shown below. [VBE(on) = 0.7 V] and also explain the theory behind the working of this circuit.

(see diagram in attached file)

2- what is the relationship between gain and bandwidth in amplifiers with negative feedback? How about positive feedback?

- what is the advantage of a cascode gain stage?
