Abstract

This circuit enables the sensitivity of a differential sense amplifier to be evaluated in dynamic memory circuits by allowing one of the differential inputs to be varied by a known percentage of its nominal value by the use of test input signals to vary the effective ratio of a resistor divider controlling the level of the reference input signal.
