Complementary voltage interpolation circuit. The invention centers around a system for interpolating between multiple pairs of main complementary signals to generate further pairs of complementary signals. An input circuit (10) supplies the main signals. The interpolation is done with two strings (12) of a selected number of impedance elements (R0 - RN-1 and RNO - RNN-1). Each pair of main signals is supplied to a corresponding pair of nodes along the strings. The interpolated signals are taken from other pairs of corresponding nodes along the strings. The interpolation system is particularly suitable for use in an analog-to-digital converter of the folding type. |
