    Fault-tolerance in integrated circuit design has become an alarming issue for circuit designers and semiconductor industries wishing to downscale transistor dimensions to their utmost. The motivation to conduct research on fault-tolerant design is backed by the observation that the noise which was ineffective in the large-dimension circuits is expected to cause a significant downgraded performance...

    A compact ultra-wideband (UWB) filter is designed by a proposed stepped impedance dual-mode resonator. The dual-mode resonator is formed by adjusting the impedance ratio. There are four resonant modes inside pass-band of the novel filter, two of which are generated by dual-mode resonator and the other two modes are produced by parallel-coupled feed lines. This results in the formulation of the nov... View full abstract»
