A method and system for providing a filter having an increased speed and decreased settling time are disclosed. The method and system comprise summing means for adding and subtracting. The method and system further comprise means coupled to the summer for providing a delay; and a clock coupled to the delay providing means. The clock determines a number of samples during a predetermined time. The clock is operated at a plurality of frequencies such that the total number of samples during the predetermined time is a predetermined number. According to the method and system disclosed, the filter has an increased speed. The increased speed of the filter can operate to extend the lifetime of power devices.

Method and system for a digital filter having improved settling time

A digital compensation circuit for calibrating a sensor includes a serial communication circuit for receiving data relating to a plurality of parameters and a plurality of registers coupled to the serial communication circuit; one of plurality of registers for reading temperature information. The digital compensation circuit further includes a digital trim circuit for adjusting the temperature information in the one of plurality of registers to a predetermined value at an initial calibration temperature. Finally, the digital compensation circuit further includes means responsive to the digital trim circuit for measuring gain and offset at a predetermined value of the physical parameter being measured.
