ABSTRACT:
An analog to digital converter circuit uses a reference voltage which increases in proportion to an intensity level of an input analog signal, or a reference signal which decreases in proportion to an intencity level of undesired signal components included in an input analog signal which AGC controlled, and thus maintains an adaptive quantizing level for a varying input signal level or a varynig desired signal level in an input signal without a DA converter.
