ABSTRACT:
A circuit and a method for generating modified reference voltages are provided. The reference voltages are modified dependent upon the level of electrical signals received. A series of electrical signals is provided to a reference voltage adjuster. The reference voltage adjuster stores a signal representing either a previous maximum or minimum signal value, and also stores a signal representing a present signal from the series of electrical signals. The reference voltage adjuster then determines the existence of a new maximum or minimum signal value. Upon the determination of the existence of a new maximum or minimum signal value, the average of the new maximum or minimum signal and the previous maximum or minimum signal value is determined. The signal representing the average of the new maximum or minimum signal and the previous maximum or minimum signal value is then provided to a comparator as the new reference voltage.
