A 7-nm All-Digital Leakage-Current-Supply Circuit for Analog LDO Dropout Voltage Reduction
IEEE Solid-State Circuits Letters, 2019A 7-nm leakage-current-supply (LCS) circuit monitors leakage across process and temperature variations and controls PFET block-head switches (BHSs) to supply the slow-changing leakage current while a high-bandwidth analog low-dropout (LDO) voltage ...

Design of an adjustable,low voltage, low dropout regulator
Proceedings of the Fifth IEEE International Caracas Conference on Devices, Circuits and Systems, 2004., 2005This paper presents the design of a low voltage, low dropout (LDO) regulator with two different output voltages (1V or 1.8V). The basic function of an LDO is to optimize the battery life of portable devices and to provide a constant output voltage to drive small sub-circuits. The proposed LDO was designed using 0.35/spl mu/m CMOS technology. The design

European Solid-State Circuits Conference, 2018
This paper presents an NMOS pseudo-digital low-dropout (PD-LDO) regulator that supports low-voltage operation by eliminating the amplifier of an analog LDO. The proposed pseudo-digital control loop consists of a latched comparator, a 2X charge pump and a

EMI Resisting Bandgap References and Low Dropout Voltage Regulators
2009This chapter examines the effects of EMI injection in the power supply of bandgap references and low dropout voltage regulators. Three major coupling paths can be distinguished when dealing with the EMI suppression of voltage regulator circuits. The first coupling path, namely the path which is responsible for corrupting and disturbing the bandgap ...

Low Dose Rate Testing on Commercial Low Dropout Voltage References
2009 IEEE Radiation Effects Data Workshop, 2009Voltage references which are suitable for low Earth orbit space missions were irradiated at low dose rate with gamma particles by INTA (Institute Nacional de Tecnica Aeroespacial). The aim of this work is to analyze the enhancement of low dose rate sensitivity in this type of devices, based on bipolar as well as CMOS technology.

Structural Design of a CMOS Full Low Dropout Voltage Regulator
2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007The paper describes structural design of a full (complete) low dropout (LDO) voltage regulator. This LDO is using the following basic subcircuits: bandgap reference (BGR), folded-cascode current operational amplifier (COA), and bias circuit. The regulator is divided in three main blocks, namely, a sub-regulator generating power supply voltage for the ...

Modeling Total-Dose Effects for a Low-Dropout Voltage Regulator
IEEE Transactions on Nuclear Science, 2006Total ionizing dose effects in a low-dropout voltage regulator are explained based on experimental data and circuit simulations. Transistor gain degradation is shown to be the dominant cause of the circuit degradation at lower dose rates. In addition, collector-to-emitter leakage current in one of the NPN transistors of the bandgap reference part of ...

Fully on-chip switched capacitor NMOS low dropout voltage regulator
Analog Integrated Circuits and Signal Processing, 2009This paper presents a 1.5 V 50 mA low dropout voltage (LDO) regulator using an NMOS transistor as the output pass element. Continuous time operation of the LDO is achieved using a new switched floating capacitor scheme that raises the gate voltage of the pass element.
