In this paper, an adaptive low drop-out linear regulator with a new compensation technique is presented, in which the off-chip capacitor occupies large area in the chip and thus not ideal for SoC applications.Abstract:
Acapacitor-less low drop-out linear regulator with a new compensation technique is presented. A conventional LDO suffers intrinsic stability problem at low load currents and require a large offchip capacitor to make LDO stable. This off-chip capacitor occupies large area in the chip and thus not ideal for SoC applications. Many LDO architectures have been proposed recently but still some of them requires off-chip capacitor and suffers due to bandwidth limitation and requires additional complex circuits. The proposed LDO architecture with a compensation network provides solution to the above problem. The proposed LDO is simulated and verified in Cadence using 180 nm CMOS technology.read more

TL;DR: It is demonstrated that in these LDOs the output voltage might be higher than the input reference voltage at minimum load current, and both the circuits begin "to follow" to achieve desired voltage with respect to load current depending on bias voltage.

On the power efficiency of cascode compensation over miller compensation in two-stage operational amplifiers
Hamed Aminzadeh,Reza Lotfi +1 more
TL;DR: Two popular techniques to stabilize two-stage operational amplifiers, namely, Miller and cascode compensations are compared from power efficiency point of view and it is shown that cascode compensation is more power-efficient than Miller compensation, especially for heavy capacitive loads.
