This paper presents a current feedback buffer based output capacitorless low-dropout (OCL-LDO) regulator. By incorporating the weighted current feedback (WCF) circuit technique in a simplified buffer-based regulator architectural design, it can provide a fast response with efficient transient figure-of-merit (FOM) for wide current (IL) and capacitive (CL) load range. Validated in a UMC 65-nm CMOS...
This paper presents a low-voltage Flipped Voltage Follower (FVF) based output-capacitorless low-dropout (OCL-LDO) regulator. It consists of a transient-enhanced push-pull (TEPP) driving stage to improve the response at low quiescent power. With simple Miller compensation (SMC) and modified damping factor control (DFC) compensation, the regulator permits small compensation capacitance for maintaining...
An ultra-low power, low-noise, high power supply rejection (PSR) op-ampless regulator is presented in this paper. It uses a native composite power transistor plus a sandwich on-chip native capacitor in the pre-regulator to enhance broadband high PSR performance. Besides, a pseudo-resistor based low-pass filter is used to reduce the Brokaw's voltage regulator circuit noise. Realized using GlobalFoundries...
Preliminary results from an investigation on the application of dynamic power flow controllers to a stretch of the Qatar Transmission System (QTS) along the western coast of Qatar. The main objective of applying the power flow controller is to maintain balance of power flow between the networks or lines that supply to this weaker region of the QTS, and in turn support network security should the demand...
