Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.

What is amplifier roll off?

A practical amplifier will contain several components of a "shunt" capacitance inherent in the transistor and physical wiring of the amplifier circuit. As the frequency of the input signal increases, the reactance of these shunt-capacitances will decrease until, at a frequency determined by the value of the shunt-capacitance and the circuit impedance, signal attenuation begins to take place. Thus the shunt capacitances limit the high-frequency response of the amplifier (note that the transistor itself also has inherent limits to it's high frequency amplifying capability). In the case of operational amplifiers, many operational amplifiers are internally compensated by a small capacitor (e.g. about 30pf for a 741). The internal frequency compensation capacitor prevents the operational amplifier from oscillating with resistive feedback.


Can you amplify DC voltages?

Yes, certainly - an operational amplifier circuit (see e.g. Wikipedia) will do this. For instance, a non-inverting amplifier circuit with a gain of 10 will give 1.0V output for 100mV input, 2.0V for 200mV, and so on (limited by the supply voltage of the amplifier). Physical sensors such as thermocouples or strain gauges often need DC amplification to make their outputs easier to measure.
