Time-based low dropout regulator
The low dropout regulator (LDO) is an essential building block for modern integrated circuits. Traditional analog design faces formidable challenges as technology scales down, such as lower supply voltage and channel length modulation. Digital LDOs do not have the problems that analog LDOs have, …

Design and analysis of an ASIC for energy harvesting applications
… voltage of the piezoelectric generators. A Low Dropout Regulator (LDO) was designed to create a steady dc output voltage of 4.1 V. The ASIC for this system was designed using 0.6μm complementary metal-oxide-semiconductor (CMOS) technology.

Modularizing the LDO to optimize performance based on application design constraints
This thesis aims to construct a modular low-dropout regulator that gives designers more freedom in building a highly efficient regulator that meets application demands. This modular design is able to separate DC regulation and high-frequency supply rejection while not compromising on either of the …

Supercapacitor-based linear converter for voltage regulator modules
… technique suitable for microprocessor voltage regulator modules (VRMs). The original linear regulator is the patented supercapacitor assisted low-dropout regulator (SCALDO). A less complex, lower cost design was achieved by reducing the number of switches in the original SCALDO and adding a …

Design of SCALDO based high-current DC power supply
… SCA technique, the supercapacitor-assisted low dropout regulator (SCALDO) combined a linear regulator in series with a supercapacitor to act as a lossless voltage dropper. SCALDO created the opportunity to develop an entirely new family of highly efficient, interference-free, …

SHARC Buoy: Robust firmware design for a novel, low-cost autonomous platform for the Antarctic Marginal Ice Zone in the Southern Ocean
… batteries in series with a temperature-resistant low dropout regulator, and a power sensor to monitor the module. A satellite modem transmitted data through the Iridium satellite network. Finally, Flash chips provided permanent data storage. Firmware and peripheral driver files were written in C …

On-chip magnetic sensor and readout design for 3D position tracking in image-guided interventions
… magnetic sensor includes a state-of-the-art low-noise analog-front-end (2.07 nV/√Hz) and a low-area continuous-time delta-sigma analog-to-digital converter (ADC) (0.07 mm2). The readout circuit also incorporates essential power management blocks such as a bandgap reference (BGR) and a …

Analysis on Supercapacitor Assisted Low Dropout (SCALDO) Regulators
… different electronic circuit blocks. Switching regulators have relatively high end-to-end efficiency, in the range of 70 to 93%, but can have issues with output noise and EMI/RFI emissions. Switched capacitor converters use a set of capacitors for energy storage and conversion. In general, …
