The Lecture is:

Compensation techniques for CMOS low dropout regulators

 

Abstract:

Low dropout linear voltage regulators (LDOs) are widely used in modern electronic systems as their good merit of fast transient response, low voltage ripple, simple application circuit, etc. Traditional LDOs feature an output capacitor with µF range to maintain the loop stability and good transient performance, where the dominant-pole compensation is often used. The first part of this talk will briefly discuss the compensation strategy of CMOS LDOs, and then introduce several compensation techniques to stabilize the LDOs with bulky off-chip capacitors, targeting for the applications of low power, high loading capability, etc.

Recent development of output-capacitorless low dropout regulators (OCL-LDOs) realizes on-chip, local voltage regulation to enable more effective integrated power management for System-on-a-Chip (SoC). In order to stabilize the OCL-LDOs with the removal of the off-chip capacitor, Miller compensation becomes an attractive alternative that offers the possibility of area-efficient integration. In the second part of this talk, several advanced frequency compensation techniques, developed from Miller compensation, will be introduced and discussed, targeting for fast transient response, full-load stability, etc.
