Abstract
A sense amplifier includes a first PMOS transistor, a second PMOS transistor, a third PMOS transistor, a fourth PMOS transistor, a first NMOS transistor, a second NMOS transistor, a third NMOS transistor, and a fourth NMOS transistor. The first PMOS transistor, the second PMOS transistor, the first NMOS transistor, and the second NMOS transistor form cross coupled sensing pairs. The third PMOS and the fourth PMOS transistors serve as compensation transistors. The third NMOS and the fourth NMOS transistors serve as sensing enabling transistors.
