WebAn output-capacitorless low-dropout regulator (OCL-LDO) with simple structure and fast transient response is proposed for system-on-chip (SoC) applications. A super source follower is inserted into a cascoded flipped voltage follower to drive the power transistor, which forms a fast-local loop for quick turn-on. A robust overshoot detection circuit … WebAn active-frequency compensation circuit is introduced in [5] to greatly ... As shown in Fig. 1, the basic structure of this ultra-fast capacitor-less LDO is similar with [13] focusing on dynamic biasing. It is constructed by two differential common-gate transconductance cells, a voltage buffer, a current-summation circuit and an ...

WebJan 31, 2013 · This paper presents a novel frequency compensation technique for a low-dropout (LDO) voltage regulator. Enhanced active feedback frequency compensation is employed to improve the frequency response. The proposed LDO is capable of providing high stability for current loads up to 150 mA with or without loading capacitors. Webcompensation methods, two zeros of the right-half plane (RHP) can be placed in the left-half plane (LHP) to prevent lagging and reduce the on-chip compensation capacitor. The current efficiency of ... WebMoreover, this loop can provide an improved dynamic response due to its increased discharging current. ... and stability without a complex frequency compensation mechanism. The proposed LDO is fabricated in the SMIC 180 nm process with a chip area of 0.046 mm $^{2}$. Measurement results indicate that this LDO can obtain a 200-mA … how to set coordinate system in microstation
