With the introduction of switch-mode power supplies (SMPS) in mid-1970s, efficiency DC–DC conversion rose from 60 to 80% and SMPS became a popular supply solution. However, linear regulators have not become obsolete. The modern management system portable devices supports complex mix converters, combining (SMPS), switched capacitor converters (SCCs), form low-dropout (LDOs). LDOs are used low-vo...

Integrated voltage regulators with a wide output current/voltage dynamic range are required to support fast dynamic voltage and frequency scaling (DVFS). Low Dropout Regulators (LDOs) based on digital-intensive circuits have been gaining popularity [1]–[4] due to their compactness, process scalability, high immunity to process-voltage-temperature (PVT) variations and easy programmability for de...

The security implications of on-chip voltage regulation on the effectiveness of various voltage/frequency scaling-based countermeasures such as random dynamic voltage and frequency scaling (RDVFS), random dynamic voltage scaling (RDVS), and aggressive voltage and frequency scaling (AVFS) are investigated. The side-channel leakage mechanisms of different on-chip voltage regulator topologies are ...

This paper presents a robust control scheme for distributed generations (DGs) in islanded mode operation of a microgrid (MG). In this strategy, assuming a dynamic slack bus with constant voltage magnitude and phase angle, nonlinear equations of the MG are solved in the slack-voltage-oriented synchronous reference frame, and the instantaneous active and reactive power reference for the slack bus...

Low-dropout (LDO) voltage regulator has fascinated industry professionals and academia for the past few decades, this trend is expected to continue in coming years. The high demand a stable linear architecture that performs well systems-on-chip (SoC) power management integrated circuits (PMICs) key factor driving innovation with different complementary metal-oxide-semiconductor (CMOS) technolog...

Abstract The problem of common mode voltage in inverters can be considered as a major issue which leads to motor bearing failures. To eliminate these voltages, proposing some methods seems to be necessary. This paper has a comparative study on estimating modulation methods of eliminating common mode voltage. The main idea of these methods is based on generation of reference vector with nearest ...

This paper describes the Designing of Low Power LOW DROP-OUT (LDO) Voltage Regulator using Bulk Modulation technique. Low-Drop-Out (LDO) voltage regulators are commonly used in electronic systems particularly in portable or low-power applications. Their main function is to provide a stable supply voltage by minimizing the ripples and noises caused by imperfect power sources and/or variable load...
