Hi,

This is a very general question about specs for any analog circuit (for example we can consider an op-amp)

Generally the specs are given in terms of gain, bandwidth and other such parameters.

Are there cases when specs might be given in terms of the frequency response.
In other words, are there cases when specs may involve more than parameters such as gain, BW, -3db, CMRR etc and a detailed freq response needs to be matched.

Your answers are very much appreciated.
