Abstract
A comparator circuit (,) includes a comparator network and a comparator enabling device (,) and may be integrated with a sense amplifier circuit (,). The comparator network is adapted to receive a complementary pair of reference data signals (B, B,) and a complementary pair of analog data signals (d1, d1b). An output of the comparator circuit (,) 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 (,) 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.
