IEEE Transactions on Circuits and Systems I: Regular Papers. 67:3740-3752
This article proposes an LDO with fast response to load transients that can handle any practical capacitive loads. These features are mainly due to a novel frequency compensation circuit tailored for its error amplifier, which is based on an improved

This paper presents a methodology for designing over-temperature and over-current protection (OTP and OCP) circuits for low drop-out voltage regulators (LDOs). The OTP monitors the die temperature developed within the LDO and disables its output stag

The actual operation of the power distribution systems asks for high power quality (PQ). This fully justifies the investments in improving the metrics of power grid performances. But maintaining a PQ data infrastructure in a numerous locations is tim

2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC).
This paper presents a design methodology based on electro-thermal simulations for the over-temperature protection (OTP) of low drop-out voltage regulators (LDO). The OTP monitors the die temperature developed within the LDO and shuts down the circuit

One of the most important causes that lead to fault in the case of induction motors is rotor eccentricity. The rotor eccentricity causes an unbalanced magnetic pull that leads to an increase in the noise level of the machine and a shorter lifespan of
