ABSTRACT:
An offset current independent sense circuit is switchable between a store state and a sense state. In the store state, the sense circuit stores an offset current to a capacitor, and the influence of the offset current is eliminated by a transistor to regenerate the offset current based on a signal provided by the capacitor in the sense state.
