摘要： An amplifier circuit with overshoot suppress scheme including an input amplifier, an output amplifier, and a diode is provided. A first and a second input ends of the output amplifier are coupled to a differential output pair of the input amplifier. The diode is coupled between an output end and the first input end of the output amplifier. When the voltage difference between the output and the input ends of the output amplifier is greater then the barrier voltage of the diode, the diode is turned on, so that the output end of the output amplifier is coupled to the input end of the output amplifier. In the transient state, it rapidly smoothes the overshoot signal. In the steady state, the diode is cut off to maintain the normal operation of the operational amplifier.

摘要： Circuits and methods for transmitting and receiving small swing differential voltage data to and from a memory are described. A plurality of memory cells is formed in arrays within a plurality of memory banks. Each memory bank is coupled to a pair of small swing differential voltage global bit lines that extend across the memory. A small signal write driver circuit is coupled to the global bit lines and configured to output a small signal differential voltage on the global bit lines during write cycles. A global sense amplifier is coupled to the global bit line pairs and configured to output a full swing voltage on a data line during a read cycle. Methods for providing small swing global bit line signals to memory cells are disclosed. The use of small swing differential voltage signals across the memory reduces power consumption and shortens memory cycle time.

摘要： A method of transporting data with embedded clock including following steps is provided. In an initial stage, a first bit length and a second bit length are determined. Original data is received. The original data is packed with every N bits as a packet, where N is at least 4. It is analyzed whether a long-run length of long-run data with consecutive same bit data in the packet is greater than N/2. The packet is coded to embed clock/toggle information with the first bit length into the packet. The clock/toggle information determines whether the long-run data is toggled. An appearance frequency of the clock/toggle information is clock information. If the long-run length is not greater than N/2, the long-run data is not toggled. If the long-run length is greater than N/2, bit with the second bit length after an Lth bit of the long-run data is toggled.
