Abstract
A static, low-power differential sense amplifier (DSA) and method includes operation of cross-linked channels having complementary differential nodes separated from ground by corresponding parallel-transistor pairs. The DSA output channels have complementary output nodes separated from ground by corresponding parallel-transistor pairs. The DSA further includes logic gates to produce a sense amplifier output. Each logic gate is driven by a corresponding complementary differential node and an opposite complimentary output node. The DSA includes transistors activating a done line under control of the complementary differential nodes.
