Abstract
A circuit includes first and second data lines, a sense amplifier including first and second input terminals, a first p-type metal-oxide-semiconductor (PMOS) transistor coupled in series with a first capacitive device between the first data line and the second input terminal, a second PMOS transistor coupled in series with a second capacitive device between the second data line and the first input terminal, a third PMOS transistor coupled between the first data line and the first input terminal, a fourth PMOS transistor coupled between the second data line and the second input terminal, a first n-type metal-oxide-semiconductor (NMOS) transistor configured to selectively couple each of the first PMOS transistor and the first capacitive device to a ground node, and a second NMOS transistor configured to selectively couple each of the second PMOS transistor and the second capacitive device to the ground node.
