Abstract:
An apparatus comprising:a regenerative amplifier for storing a differentially sensed input value, the regenerative amplifier comprisinga first inverter having a first input and a first output; anda second inverter having a second input and a second output, the second input being coupled to the first output, the second output being coupled to the first input;a load circuit coupled on a first line between a first reference power rail and the first input and coupled on a second line between the first reference power rail and the second input; anda current steering combinational network coupled to the regenerative amplifier, the current steering combinational network coupled to receive at least one digital data signal for performing a logical function upon the data signal, the current steering combinational network includinga first current steering circuit for steering current to the first input when a result of the logical function has a first value and for steering current from the first input when the result of the logical function has a second value;a second current steering circuit for steering current to the second input when the result of the logical function has the second value and for steering current from the second input when the result of the logical function has the first value.
