A Low-Voltage CMOS Low-Dropout Regulator With Novel Capacitor-Multiplier Frequency Compensation Zushu Yan 1, Liangguo Shen2, Yuanfu Zhao, Senior Member, IEEE, and Suge Yue1 1 Beijing ...
Capacitors are made within a given tolerance. The IEEE standard allows reactive power to range between 100% and 110% when applied at rated sinusoidal voltage and frequency (at 25 C case and internal temperature) (IEEE Std. 18-2002). In practice, most units are from +0.5% to +4.0%, and a given batch is normally very uniform. ...
In this paper, a capacitor-less flipped voltage follower (FVF) low dropout (LDO) regulator using nested miller compensation with a large feed-forward transconductor (NMCLFT) is presented. The LDO regulator is a dual -summing based three-stage high-gain structure and NMCLFT stabilizes the feedback loop for the load current ranges of 0 to 50 mA with load …

If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …
