Abstract
A bias control circuit for controlling the bias current in a sense amplifier circuit. The bias control circuit maintains a substantially constant bias current when the V.sub.CC supply voltage decreases, thereby maintaining the operating speed of the sense amplifier circuit at a predetermined level. The bias control circuit also increases the bias current as the temperature of the sense amplifier circuit increases, thereby maintaining the operating speed of the sense amplifier circuit at the predetermined level. Furthermore, the bias circuit controls the logic low voltage provided by the sense amplifier circuit to be less than a predetermined threshold value, even as the V.sub.CC supply voltage increases.
