ABSTRACT:
A differential sense amplifier is provided wherein a first amplifier stage is biased to minimize current consumption of all stages of the amplifier and to provide outputs of the first stage that are high enough in voltage to allow proper operation of a second stage of the amplifier, yet low enough in voltage to allow a current mirror to be integrated into the second stage of the amplifier. The integration of the third stage current mirror into the second stage amplifier reduces capacitive loading on the outputs of the second stage increasing speed while eliminating the extra power normally associated with a separate current mirror. This combination results in a very fast, yet very low power amplifier.
