Abstract:
A method for converting analog signals to digital signals comprising:introducing an analog input voltage to a plurality of cells; introducing a reference voltage to the plurality of cells; receiving the analog input voltage on a first input terminal of each of the plurality of cells; receiving the reference voltage on a second input terminal of each of the plurality of cells; providing an output signal across a first and second output terminal of each of the plurality of cells; coupling a first set of impedance elements to the respective first and second output terminals of each of the plurality of cells; and coupling a subset of a second set of impedance elements between the respective first output terminals of adjacent cells and coupling the remainder of the second set of impedance elements between the respective second output terminals of adjacent cells, wherein the second set of impedance elements provide relatively small impedance values compared with the first set of impedance elements.
