    摘要: A method and apparatus is provided that solves the problem of data overrun and underrun, for example in a system that exchanges data using the Gigabit Ethernet protocol. A single 8-bit data path is provided as output and the main protocol state machines are kept running in the clock domain of the rest of the circuit, after an elasticity FIFO, so that no additional synchronization is necessary. The invention makes no demands upon the receive clock other than those specified in the relevant standard for duty cycle and accuracy. The invention correctly combines the two effective data streams back into a single data stream, only modifying the FIFO when it is acceptable to do so, and in a way that does not corrupt data packets passing through the FIFO. By providing a minimal set of logic running in the receive clock domain, it is possible to simplify the design of the main protocol state machines. Only a very small portion of the design must be aware of the dual-clock nature of the physical interface. In addition, because all key state machines are no longer in the receive clock domain, any state information or registers are available even if the receive clocks are not running correctly, as is the case with a removable transceiver design.

    摘要: A monolithic amplifier includes a stable, high resistance feedback circuit and a dynamic bias circuit. The dynamic bias circuit is formed with active elements matched to those in the amplifier and feedback circuit to compensate for variations in the operating and threshold voltages thereby maintaining a stable resistance in the feedback circuit.

    摘要: A process is disclosed for converting biomass to fuels and/or valuable chemicals. The process comprises the steps of a) activating biomass to make it more susceptible to conversion; c) partially converting the biomass to a solubilized material; and d) subjecting the unconverted biomass to a second conversion step. The process optionally comprises a step b) of adding a solvent to the activated biomass. In a preferred embodiment the solubilized biomass obtained in step c) is removed before the unconverted biomass is subjected to step d).
