—The design issues of a single-transistor-control (STC) low-drop-out (LDO) based on flipped voltage follower is discussed in this paper, in particular the feedback stability at different conditions of output capacitors, equivalent series resistances (ESRs) and load current. Based on the analysis, an STC LDO was implemented in a standard 0.35-m CMOS… (More)
In order to be useful for mobile systems, the switching frequencies of modern buck converters (BCs) are in the MHz-or even GHz-range to enable the use of compact off-chip inductors and capacitors , or even on-chip Ls and Cs . However, such high switching frequencies increase both the switching loss and the gate-drive loss, and degrade BC light-load… (More)
