چکیده

A solution to the stability of capacitor-less low-dropout regulators with a 4pF Miller capacitor in Multi-level current amplifier is proposed. With the Miller compensation, a more than 50°phase margin is guaranteed in full load. An extra fast transient circuit is adopted to reduce stable time and peak voltage. When the load changes from light to heavy, the peak voltage is 40mV and chip quiescent current is only 45uA.

13th Int'l Symposium on Quality Electronic Design

Experimental results of an active filter based onchip hybrid voltage converter are described in this paper. The area of the voltage converter is significantly less than the area of a conventional passive filter based DC-DC voltage converter or a low-dropout (LDO) regulator. Hence, the proposed circuit is appropriate for point-of-load voltage regulation for the noise sensitive portions of an int...
