One contact end connects a first end of an AC source, and a control end connects a second end of the AC source. A second path is composed of two contact ends of a second electronic switch and a second, fourth and sixth diodes, which connect in series. One contact end connects the second end of the AC source, and a control end connects the first end of the AC source. The AC source is connected between the positive ends of the first and second diodes.

摘要： A low noise amplifier with back-to-back connected diodes and a back-to-back connected diode with high impedance thereof are provided. The low noise amplifier includes a first operational amplifier (OP) and at least two first back-to-back connected diodes. The back-to-back connected diode with high impedance is formed from at least one MOS FET operated within a cut-off region. The first back-to-back connected diodes are connected electrically between the first input end and the first output end, and between the second input end and the second output end, of the first OP respectively. By the implementation of the present invention, the low noise amplifier is not only low noise, but also with low energy consumption, high stability, low circuitry complexity, and easily controlled manufacturing process.

摘要： The present invention comprises an efficient system and method for reading and writing data from memory that is organized to represent either field or frame video data in a wide-word configured memory. A memory controller is configured to read or write either sequential wide-words or alternate wide-words in a DMA transfer as directed by software. After the DMA transfer is initiated, the memory read or write operations proceed automatically until the DMA transfer is completed. The ability to read or write either sequential or alternate wide-words beneficially supports operations to convert between field video data for interlaced video displays and frame video data for progressive-scan displays.

摘要： The present invention comprises a system and method for flexibly distributing timing signals. Timing signals may require varying delays when connected, via circuit paths of varying propagation delays, to multiple circuit elements in order to preserve circuit synchronization. In one embodiment of the present invention, multiple clock signal generators are programmed to produce clock signals of differing time delays. This programming may be accomplished after the design and fabrication of the circuits utilizing the clock signals. These clock signals are then distributed, via circuit paths of varying propagation delays, to the multiple circuit elements.

摘要： The present invention comprises an efficient system and method for writing specific bytes in a wide-word configured memory. A memory controller is configured to write from a wide-word databus to specific bytes in a wide-word addressed memory. The memory controller uses wide-word memory addresses which possess resolution capable of addressing specific bytes, and, in addition, data mask bytes which inhibit data write operations to those bytes in a wide-word which are not intended to be written in a given memory write operation. In one embodiment of the present invention, data mask bytes are created by shifting predetermined bit patterns to the right by an amount calculated by arithmetically combining bits in the wide-word memory address. A flexible individual address generating scheme allows memory write operations which do not depend upon the memory write operation's data boundaries being evenly aligned with the boundaries of wide-words.
