Integrated Circuit Signal Delay
Technologies for designing and building microelectronics-based computational equipment have been steadily advancing ever since the first commercial discrete circuits (ICs) were introduced in the late 1950s (1) (monolithic integrated circuits were introduced in the 1960s). As predicted by Moore's law in the 1960s (2), integrated-circuit density has been doubling approximately every 18 months, an...
متن کاملNegative Group Delay and Superluminal Propagation: An Electronic Circuit Approach
We present a simple electronic circuit which provides negative group delays for band-limited, base-band pulses. It is shown that large time advancement comparable to the pulse width can be achieved with appropriate cascading of negative-delay circuits but eventually the out-of-band gain limits the number of cascading. The relations to superluminality and causality are also discussed.
متن کاملPID-Fuzzy Control Method with Time Delay Compensation for Hybrid Active Power Filter with Injection Circuit
Due to inherent time delays in the control system of Hybrid Active Power Filter with Injection Circuit (IHAPF) and the load harmonic currents changes rapidly and dramatically. In order to eliminate these harmonic currents, an IHAPF to be used must be able to respond quickly following variable of the harmonic currents. So, this paper proposes a PID-fuzzy control method with time-delay compensati...
متن کاملDesign of an Active Approach for Detection, Estimation and Short-Circuit Stator Fault Tolerant Control in Induction Motors
Three phase induction motors have many applications in industries. Consequently, detecting and estimating the fault and compensate it in a way that the faulty induction motor satisfies the predefined goals are important issues. One of the most common faults in induction motors is the short circuit of the stator winding. In this paper, an active fault-tolerant control system is designed and pres...
متن کاملAn integrated active-quenching circuit for single-photon avalanche diodes
We introduce the first integrated active quenching circuit (I-AQC) that drives an avalanche photodiode (APD) above its breakdown voltage, in order to detect single photons. Based on the I-AQC, we developed a compact and versatile photon-counting module suitable for applications in which very weak optical signals have to be detected, as for instance, photon correlation spectroscopy, luminescence...
