ABSTRACT:
A parallel type analog to digital (A/D) converter in which an input signal and reference voltages are differentially amplified by differential converting circuits, interpolation resistors are inserted between the outputs and between the complementary outputs of the differential converting circuits, and a tap voltage between the interpolation resistors is A/D converted, so that the A/D converter can operate at a high accuracy and at a high speed.
