    Abstract: A current interpolation circuit for use in an A/D converter is disclosed. The current interpolation circuit comprises current division circuits or current mirror circuits. Several reference voltages are converted into positive currents and negative currents by some folding amplifiers. Then the positive currents and the negative currents are fed to the current division circuits or the current mirror circuits, generating some positive currents and negative currents. Finally, a number of current comparators are configured to receive the generated positive currents and negative currents to produce differential voltage signals which are then used as interpolated levels.
