    How DC amplifiers depend on frequency.

    You can make an amplifier for DC that has a frequency response up to a few megahertz if you want.

    Exactly what do you want the amplifier to do? Say all the details.

    What is the method to get expression for DC amplifiers frequency responce.

    A Bode plot gives the best idea of frequency response in a visual format. There are far too many frequencies and possible problem areas (peaks, phase, etc) to give frequency response a single number, such as is done with distortion.

    All the plots we draw on the basis of expression we derived.We have to derive the expression.

    Basicaly this depend on stray capacitances that exist in the circuit.But I can not find the expression and dependency on frequency.This is also important because if this is due to stray capacitances ,it is unexpected result.
