Abstract
A current source varies the bias current to a differential amplifier according to fluctuations in the supply voltage. In this manner, the operating point of the differential amplifier is automatically adjusted to compensate for variations in the supply voltage. Adjusting bias current in this manner provides for a reduction in power dissipation. The current supply is coupled to the differential amplifier in such a manner that a current mirror is not required to be connected between the differential amplifier and the inverter. Eliminating the need for such a current mirror is advantageous in reducing the number of gate delays and thereby increasing the speed of a level translator to which the current source is coupled.
