摘要： The present invention relates to a level converter used in a multiple supply voltage system that is required to design a low-power and high-performance semiconductor, and more particularly, to a single supply pass gate level converter (SPLC) for a multiple supply voltage system, which has low power consumption, operates at high speed, and uses only a single supply voltage. The SPLC includes an input data providing circuit unit which receives an input signal of a low supply voltage; a data inversion circuit unit which receives input data from the input data providing circuit unit and outputs inversed input data; a feedback circuit unit which is fed back by an output of the data inversion circuit unit; and a data output buffer which inverses an output of the data inversion circuit unit and outputs an inversed signal. The input data providing circuit unit, the data inversion circuit unit, the feedback circuit unit, and the data output buffer are all driven by a high supply voltage such that only a single supply voltage which is the high supply voltage is required.

摘要： A method of channel coding a digital communication system and a device using the same is provided. The method includes quantizing analog data to digital data, the digital data corresponding to a predetermined number of digital codes; allocating channel codes to the digital codes, as a Hamming distance between a pair of channel codes corresponding to any pair of the digital codes is proportional to a difference between analog values of the pair of the digital codes; and channel coding the digital data by using the channel codes which are allocated to the digital codes to generate channel coded digital data. Accordingly, digital data, such as multimedia digital data without source coding and the like, of which information significance is different may be effectively transmitted and received.
