Delay-locked loop with dual loop filters for fast response and wide frequency and delay range
A delay-lock loop includes two feedback loops for controlling delay elements in the delay-lock loop. The first feedback loop includes a feedback circuit for generating a feedback signal indicating a delay adjustment based on a phase difference between an input clock signal to the delay-locked loop and an output clock signal generated by the delay-locked loop.

An apparatus including a flexible substrate; a component supported by the flexible substrate; a first input electrode, supported by the flexible substrate and configured to form a first capacitor with a second input electrode and to provide an input to the component; and a first output electrode, supported by the flexible substrate and configured to form a second capacitor with a second output electrode and to provide an output from the component.. .
Abnormality detection circuit for electric storage unit and abnormality detecting method for electric storage unit
A capacitor has modules each consisting of a plurality of capacitor cells stacked together, and a radiator including heat exchange portions connected to a vehicle body at the ground potential is disposed adjacent to the modules. If an electric leakage occurs to any of the capacitor cells, a leakage detection voltage as a potential difference between the potential of the cell under the leakage and the ground potential is correlated with a module voltage, to provide a constant ratio, from which it is determined that the capacitor is in an abnormal condition..
