This paper proposes a digital delay locked loop (DLL) with monotonic line (DL). DLL adopts the calibration mode to reduce non-monotonic effects for coarse-tuning (CTDL) and fine-tuning (FTDL). The detects time of unit, timing resolution CTDL, adjust range FTDL. Thus, can limit overlap between CTDL proposed was implemented using 0.18-μm CMOS process, RMS peak-to-peak jitters were 0.21% 1.72%, re...

introduction: delay in the diagnosis of tuberculosis increases the risk of death and enhances the transmission of disease in the community. this study aims to determine the patient and health service delay and factors affecting it in tuberculosis diagnosis. materials & methods: a cross-sectional survey that included all the public health centers was conducted in markazi province from march 2009...

This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...
