Abstract
A resistor in a pair of resistors is selectively coupled to a current source through a selection switch during the reset phase of a voltage-mode sense amplifier so that one evaluation node for the voltage-mode sense amplifier is discharged from a power supply voltage by an ohmic voltage drop across the selectively-coupled resistor to null an offset for the voltage-mode sense amplifier.
