Input circuit configurations that reduce the amount of input signal jitter caused by a common input signal return path, methods and circuits utilizing the same are provided. Input signal return path noise may be decoupled from the power for receiver circuits, for example, by utilizing separate power supply lines, such as VDDQ and VSSQ, as input signal return path.

Disclosed is a separator for a fuel cell made of a metal plate coated with TiN, a polymer electrolyte membrane fuel cell comprising the separator and a method for manufacturing the separator. According to the invention, the separator can be made to be thin and it is possible to increase the power density, compared to the prior separator made of graphite. At the same time, a proper level of physical strength can be maintained, so that there is no problem of a breakdown by an external shock. In addition, the flow field can be easily formed and the cost is low. Additionally, the polymer electrolyte membrane fuel cell comprising the separator using a metal plate coated with TiN according to the invention has no problem of corrosion of metal separator due to the electrolyte, compared to the prior metal separator, so that the durability is excellent and the lifetime is long. In addition, when a mass-production system is established, the flow fields are provided by stamping a thin metal plate instead of forming the flow fields on the stainless steel plate, and then the two plates are brazed and coated with TiN, so that the weight of the stack is decreased.

A method and apparatus for ensuring safe transmission of data on a bus line. In one embodiment, within a given clock period, first data is driven on a data bus and a strobe signal is transmitted, via a first signal path, to a receiving circuit indicating the validity of the first data on the data bus. A return signal received within the given clock period indicates an assumed arrival of the strobe signal at the receiving circuit. In response to receiving the return signal, second data is driven onto the data bus.

Sensing operations involving a first array of bit line sense amplifiers (BLSAs) may be powered by an upper reference voltage and a first intermediate voltage and the first array may be precharged to a voltage level therebetween. Sensing operations involving a second array of BLSAs may be powered by a second intermediate voltage (greater than the first intermediate voltage) and a lower reference voltage and the second array may be precharged to a voltage level therebetween. After precharge, charge may be transferred from a second power line of the first array to a first power line of the second array. Subsequently, the second power line of the first array may be coupled to a power supply node at the first intermediate voltage level and the first power line of the second array may be coupled to a power supply node at the second intermediate voltage level.

A separation plate having a gas flow path is segmented for analyzing MEA performance without segmenting an electrode or a gas diffusion layer. In advance, a MEA is operated for a long time in a real stack environment using a typical separation plate which is not segmented, and then the segmented separation plate for analyzing MEA performance is mounted to the MEA.
摘要:
A synchronous output signal generated by an integrated circuit (IC) component is synchronized to an applied clock signal for each individual IC component. A variable feedback delay in the IC component is incrementally altered to alter the phase skew between the clock signal and the output signal. The relative phase order of the clock and output signals is monitored in the IC component. In response to detecting a swap in the relative phase order of the clock and output signals, the variable feedback delay ceases to be altered. In some embodiments, the IC component may be a SDRAM component.
