ABSTRACT:
An improved analog to digital converter suitable for fabrication on an integrated circuit and operable at high speed is disclosed.
The converter is of the type when a voltage generated by a built-in D/A converter is successively subtracted from an input analog signal and the digital code of the built-in D/A converter is derived as the digital output when the coincidence between the voltage generated by the D/A converter and the input analog signal is detected by a comparator. The output of the comparator is fed back and superposed on the subtracted result as well as being used to control the D/A converter.
