Abstract
A sense amplifier circuit for low voltage applications is provided. In one implementation, the sense amplifier circuit includes a reference current generation circuit coupled to a power supply. The reference current generation circuit generates a reference current that varies linearly with respect to changes in voltages of the power supply. The sense amplifier circuit further includes a sensing circuit coupled to the reference current generation circuit. The sensing circuit senses an amplitude of a current based at least on part on the reference current.
