A fast self-reacting capacitor-less low-dropout regulator
2011 Proceedings of the ESSCIRC (ESSCIRC), 2011A fast self-reacting (FSR) low-dropout (LDO) regulator with triple transient improved loops was implemented in 0.35μm CMOS technology. The proposed regulator for SoC application can achieve high stability for load current from zero to 100mA. The FSR loops can accelerate load transient responses while the regulator achieves the FOM of only 0.00675 (ps ...

An electrolytic capacitor‐less LED driver with interleaving flyback topology
International Journal of Circuit Theory and Applications, 2015SummaryHere, we propose a single‐stage alternating current/direct current electrolytic capacitor‐less light‐emitting diode (LED) driver, which applies interleaving flyback topology to reduce the peak‐to‐average ratio of LED driving current. With this approach, the peak current through LEDs is reduced, so the lifetime requirement of LEDs can be ...

Capacitor-less D-STATCOM for reactive power compensation
2018 IEEE 12th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG 2018), 2018This paper presents a D-STATCOM for reactive power compensation in a distribution system that uses inductive energy storage element connected to the grid via a matrix converter (MC). The MC is controlled using model predictive controller (MPC) technique. The D-STATCOM will provide load compensation without using electrolytic capacitors.

A novel capacitor-less DRAM with raised source structure
2014 12th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT), 2014We proposed a new 1T-DRAM cell with raised source structure. The cell using the raised source region can achieve the characteristics of long gate length one in a limited area and it can suppress short channel effects to improve the gate controllability.

A Capacitor-less Low Drop out Voltage Regulator
2010 INTERNATIONAL CONFERENCE ON COMMUNICATION CONTROL AND COMPUTING TECHNOLOGIES, 2010Low dropout voltage regulators (LDO) use a large external capacitor, in the range of few micro-farads. These external capacitors occupy valuable board space, increase the IC pin count and prohibit System-On-Chip (SoC) solutions. The large external capacitor is replaced with a reasonable 1nF internal capacitor.

An Electrolytic capacitor-less bi-directional EV-Charger with 6 switches
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016in this paper, a new single-stage isolated bi-directional AC-DC converter with the appropriate controller for Electric Vehicle application is proposed. The topology uses only 6 active switches. Single-stage power conversion reduces the cost and volume. Instead of using an Electrolytic capacitor with limited life-time, it uses a film capacitor.

Settling Time Enhancement of Output Capacitor-Less Low-Dropout Regulator
2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019An output capacitor-less (OCL) low-dropout regulator (LDO) with a buffer and a slew-rate enhancement (SRE) circuit. By using the proposed SRE circuit, the transient response is improved. Moreover, the circuit stability can also be enhanced. The proposed voltage regulator is simulated by Spice simulation tool with a 5V power supply.

An output-capacitor-less low-dropout regulator with transient-improved technique
2017 IEEE 12th International Conference on ASIC (ASICON), 2017A transient-improved output-capacitor-less low-dropout (LDO) regulator based on single Miller capacitor feedforward compensation (SMFFC) is presented in this paper. With the SMFFC, the slew-rate at the gate of power transistor is enhanced, which results in an improved transient response during a fast load current transient.
