14.5 A 0.6-to-1.1V Computationally Regulated Digital LDO with 2.79-Cycle Mean Settling Time and Autonomous Runtime Gain Tracking in 65nm CMOS Abstract: Low-Dropout Regulators (LDOs) play an important role in enabling fine-grained supply …

2021年1月26日 · AMD’s Ryzen 5000 Mobile chips bring the 7nm process paired with Zen 3’s 19% IPC increase to notebooks for the first time, largely by replacing the Zen 2 CPU cores with faster Zen 3 cores while...

Whether MGTVTT supply requires dedicated LDO? In one of my design, Power line is shared between VDDQ supply of DDR4 (1.2V) and MGTVTT for KU115 FPGA. 1.2V Power is generated by the regulator which has Sink-Source capacity (LTM4632). Is there any issue if I am sharing the supply between VDDQ and MGTVTT ?

2017年3月14日 · Zen的稳压用的是基于芯片的低压差线性稳压器（LDO）。 英特尔的Haswell和Broadwell用的也是基于芯片的稳压器，但那是更复杂而低效的一种（全集成式电压调节模块，FIVR）。

In 2014, AMD set a bold “25x20” goal to deliver at least 25X more energy efficiency in our mobile processors by 2020. Visit AMD.com/25x20. Slide 2: Based on AMD testing as of 9/28/2017. System configuration(s): AMD Reference Motherboard (2700U), HP ENVY X360 (FX-9800P/”7th Gen APU”), Samsung 850 Pro SSD, Windows 10 x64 1703, 1920x1080.

The Excel file contains the digital low-dropout voltage regulators (DLDO) published in 2010--2020. It contains the reported and estimated parameters and metrics of each regulator. The parameter/metric definition can be found in the table below.

Are there specific recommendations about which rail needs to be supplied through LDO or Filtered? For example, the following URLs might be helpful for you.

This paper presents a review of the recent digital low-dropout voltage regulators (DLDOs). We have reviewed them in five aspects: control laws, triggering metho.
