    摘要: System, method and computer program product for setting phase control codes to (in-phase) I and (quadrature) Q rotators to a first code pair, different by enough to produce a phase difference between the rotator outputs sufficient to be detected with minimal error by a phase-to-voltage converter. Auxiliary trim DACs are then adjusted according to calibration logic until a comparator output detects a phase difference between the I and Q rotators are within tolerable limits. The resulting trim codes are stored for both the codes in the pair. These trim codes along with the main codes are subsequently applied whenever the codes are used thereafter. These steps are repeated with each successive code pair having the same separation as the first code pair, e.g. both incremented by same amount until all codes have been calibrated. In this manner having the phase separation between all code pairs forced to the same value.

    摘要: Embodiments are directed to a self-reference STT-MRAM sensing scheme that uses offset-cancellation to reduce the impact of FET mismatch and thereby allow the sensing of lower read voltages. In some embodiments, the sensing scheme includes a differential amplifier having a first input connected to a memory cell. In some embodiments, a second input of the differential amplifier may be connected to ground, a common mode voltage of the system or a mid-level supply voltage. The present disclosure provides flexibility with respect to the voltage level at which the sensing is performed (e.g., ground, Voc, Vmid, etc.). The present disclosure provides further flexibility with respect to the sense voltage polarity.

    摘要: Systems and methods for reducing process sensitivity in integrated circuit (“IC”) fabrication. An integrated circuit structure is provided that includes a first integrated circuit device having at least one parameter influenced by process variation in a first manner. The integrated circuit structure further includes a second integrated device having the least one parameter influenced by the process variation in a second manner. The first manner is opposite of the second manner. The second integrated device is configured to offset or reduce the influence of the process variation on the at least one parameter in the first integrated circuit device.
