A Fast Transient Response Capacitor-Less LDO with Transient Enhancement Technology

Micromachines
This paper proposes a fast transient load response capacitor-less low-dropout regulator (CL-LDO) for digital analog hybrid circuits in the 180 nm process, capable of converting input voltages from 1.2 V to 1.8 V into an output voltage of 1 V.

Single transistor-control low-dropout regulator

, 2011
A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot,

Exit Exams and High School Dropout [PDF]

In this paper, I consider the impact of the expansion of exams students must pass in order to graduate high school on dropout rates. "Exit exams," as these tests are known, have become more common, and more difficult.

A CMOS Low Dropout Voltage Regulator with Full-Range Stability

, 2007
穩定度一直是在設計低壓降線性穩壓器的過程中一個重要的議題。在傳統的電路架構中，負載電流大小以及輸出電容值為兩項主要影響穩定度的因素。因此，到目前為止已有許多補償的方法被提出來改善整體的效能。就應用的方面來說大致分為輸出電容外接和內建兩類，利用電容外接的方式可增加輸出電容的容值並產生一個主極點維持穩定，主要應用在系統較大對於面積較不注重的產品如電視。另一類的低壓降線性穩壓器的輸出電容靠著米勒效應使得電容值小且可整合在晶片當中，省下不少面積因此適合應用在可攜式電子產品裡作為穩定的直流電壓源 ...

A Cost-Efficient LDO Regulator Using a Dual-Loop Low-Impedance Buffer and a PT-Compensated Bias Based on the Current-Subtraction Technique

IEEE Access
This work proposes a cost-efficient, low-dropout (LDO) regulator. By employing the proposed novel Dual-Loop Low-Impedance (LI) Buffer, the second and third poles are shifted to higher frequencies. Thus, no additional resistor and capacitor (RC) frequency
