Abstract
A circuit includes a current generating circuit and a sense amplifier. The current generating circuit includes a first current mirror that generates a first current having a first current value less than a value of a first cell current through a first reference cell, and based on a ratio of the first cell current to the first current. A second current mirror generates a second current having a second current value less than a value of a second cell current through a second reference cell, and based on a ratio of the second cell current to the second current. The current generating circuit generates a reference current having a reference current value based on the first and second current values. The sense amplifier receives a third current having a third current value and generates a voltage output based on the reference and third current values.
