  • Patent number: 11942955
    Abstract: A delay locked loop circuit includes a delay line, a phase detector, a selection controller, and a charge pump. The delay line delays, based on a delay control voltage, a reference clock signal to generate an internal clock signal and a feedback clock signal. The phase detector compares phases of the internal clock signal and the feedback clock signal to generate a first detection signal and a second detection signal. The selection controller provides the reference clock signal as an up-signal and a down-signal. The charge pump generates the delay control voltage based on the up-signal and the down-signal.

  • Publication number: 20240079609
    Abstract: A separator for a fuel cell includes a reaction region, a pair of manifold regions on opposite sides of the reaction region and through which a plurality of manifolds pass, configured to introduce or discharge reaction gas or coolant, and a pair of diffusion regions between the reaction region and the manifold regions, configured to diffuse a flow of the reaction gas or coolant. Diffusion ribs in the diffusion regions are spaced apart from each other along the manifolds. The diffusion ribs may be spaced apart such that diffusion flow fields formed between the diffusion ribs have different cross-sectional areas for respective regions at ends adjacent to the manifold regions.
