This paper presents a general methodology for compensating LDO regulators which exploits a current amplifier to effectively multiply the Miller capacitor. After a general theoretical analysis that takes into account both the external and internal loop stability, it is examined the feasibility of applying this kind of compensation in different LDO applications, showing the role of the design parameters and proposing a specific design procedure for each practical cases which differ in terms of load capacitance and the adoption of a decoupling voltage buffer. Simulations and experimental results which validate the methodology are also included. |
