    摘要: A differential system producing differential signals with offset cancellation utilizing a double differential input pair system is disclosed. It uses two parallel differential transistor pairs which are intentionally skewed. Nominally, the differential pairs are skewed in opposite direction from each, but with equal magnitude, so that the combination of the two differential pairs is nominally balanced. The current through each differential pair is then increased or decreased until any offset is sufficiently cancelled, using a selection means for providing an equi-potential value to first and second differential inputs in a calibration mode of the system and a comparison means for comparing first and second differential outputs in a calibration mode to determine the offset of the system.

    摘要: Design structures, method and systems of powering on an integrated circuit (IC) are disclosed. In one embodiment, the system includes a region in the IC including functional logic, a temperature sensor for sensing a temperature in the region when the IC is powered up and a heating element therefor; a processing unit including: a comparator for comparing the temperature against a predetermined temperature value, a controller, which in the case that the temperature is below the predetermined temperature value, delays functional operation of the IC and controls heating of the region of the IC, and a monitor for monitoring the temperature in the region; and wherein the controller, in the case that the temperature rises above the predetermined temperature value, ceases the heating and initiates functional operation of the IC.
