Abstract
A sense amplifier includes a first transistor having a first gate, a second transistor having a second gate in series with the first transistor, a third transistor having a third gate, and a fourth transistor having a fourth gate in series with the third transistor. A first input node is coupled to the third gate and the fourth gate, a second input node is coupled to the first gate and the second gate, and a first compensation transistor is in series with the first and second transistors or the third and fourth transistors, the first compensation transistor having a first compensation bulk. The first compensation bulk receives a first compensation voltage to modify the first compensation threshold, the first compensation voltage having a value calculated to compensate for an offset associated with the first and second input nodes.
