摘要

Example reference current distribution circuitry described herein include current mirrors having resistive elements of varying sizes between gate nodes of sense amplifier transistors along a voltage, distribution line. Examples of counter coupling capacitances which may be coupled to the gate nodes of sense amplifier transistors are also described.
