Abstract
An amplification circuit includes: a sense amplification circuit including a read node, a complementary read node, a first node and a second node; an isolation circuit, which couples the read node to a bit line and couples the complementary read node to a complementary bit line in a sense amplification stage; an offset cancellation circuit, which couples the bit line to the complementary read node and couple the complementary bit line to read node in an offset cancellation stage; and a first power supply circuit, coupled to the first node, including a first power supply and a second power supply, a power supply voltage of the first power supply being higher than that of the second power supply, the first power supply circuit couples the first power supply to the first node in offset cancellation stage, and couples the second power supply to the first node in sense amplification stage.
