  • Patent number: 11668612
    Abstract: A method for trimming analog temperature sensors. First, raise a temperature of a temperature sensor to a highest temperature of a qualification temperature range. Then, trim the temperature sensor such that a high temperature code generated by the temperature sensor represents an actual temperature reported by the temperature sensor at the highest temperature. Next, lower the temperature of the temperature sensor to a lowest temperature of the qualification temperature range. Determine a slope error between the high temperature code and a low temperature code generated by the temperature sensor at the lowest temperature. Finally, determine a correction function that compensates for the slope error of measured temperature codes generated by the temperature sensor for temperatures across the qualification temperature range.

  • Patent number: 11381164
    Abstract: A charge pump includes first and second multiplier stages including first and second capacitor in series with an input node, a final multiplier stage including an output capacitor in series with the second capacitor and an output node, and pre-charge circuitry. The pre-charge circuitry is configured to charge the output capacitor to a first level during an initial phase of a charging operation, wherein the first level is equal to a supply voltage of the data storage system, and decouple a charging path of the pre-charge circuitry from the output capacitor in response to the output capacitor being charged to the first level. The first and second multiplier stages are configured to increase the charge of the output capacitor to second and third levels higher than the first level during second and third phases of the charging operation.
