摘要： A comparator circuit (40) includes a comparator network and a comparator enabling device (80) and may be integrated with a sense amplifier circuit (41). The comparator network is adapted to receive a complementary pair of reference data signals (B, B13) and a complementary pair of analog data signals (d1, d1b). An output of the comparator circuit (40) represents a comparison of the data represented by the reference data signals and the data represented by the analog data signals. The comparator output is generated in response to a comparator enable signal (SE) applied to the comparator enabling device (80) while the input data is applied to the comparator network. The comparator enable signal (SE) is applied at a time when the analog data signals (d1, d1b) have developed a minimum differential level.
