    摘要: A multi-phase buck converter has a digital compensator to select a set of compensation coefficients depending on the operating phase number of the multi-phase buck converter, or including different compensators for each operation phase number to improve the loop gain bandwidth, transient response and stability of the multi-phase buck converter. The multi-phase buck converter operates with more phase circuits for higher loading and operates with fewer phase circuits for lower loading. The compensation varies with the number of the operated phase circuits so to be adaptive to the operation condition with an optimized control-to-output voltage transfer function.

    摘要: An expandable decoding circuit includes a latch unit, a latch result selecting unit, and at least one decoding circuit. The latch unit latches raw data and outputs the latch values and the latch inverse-values of the raw data. The latch result selecting unit composes the latch values and the latch inverse-values according to the target decoding value of the decoding unit to generate a pre-decoding value. The latch result selecting unit outputs the pre-decoding value to the corresponding decoding unit. The decoding circuit determines whether a decoding signal is outputted or not according to the pre-decoding value. Thereby, when a new function needs to be added to the deciding circuit, the present invention does not change the original decoding circuit and implements the decoding unit for the new function.

    摘要: A method to speed up the execution of repeatable commands and a microcontroller able to speed up the execution of repeatable commands are disclosed. When the microcontroller is to execute repeatable commands in a program, it temporarily stores repeatable commands to a storage unit. If the execution of the repeatable command loop continues, then the repeatable command loop is retrieved from the storage unit and executed at higher clock cycle frequency. At the start and end of the repeatable command loop are respectively defined by a starting point and an end point for determining whether the repeatable command loop should continue to execute. The microcontroller thereby speeds up the execution of the repeatable command and the performance thereof.
