A method of mass spectrometry is disclosed comprising separating ions according to one or more physico-chemical properties. A capacitor structure having the high capacitance needed for logic elements is obtained without increasing the number of layers for fabricating the capacitor by forming a three-dimensional capacitor in the damascene pattern while maintaining the conventional processes in a damascene interconnection process. The circuit can remove such distortion from the input signal without substantially delaying the input signal. The method also includes utilizing pipelining to transmit the digital content stream over the at least one tested network connection based on a first response to the first data request and a second response to the second data request.
