Abstract
This paper presents an approach to utilize of sliding-mode (SM) controller in digital low-dropout/linear regulators. Various design aspects, including the extraction of the regulator state-space model and sliding coefficients by considering the hitting, existence, and stability conditions are described. Moreover, the freeze control block is introduced as a solution to compensate the high frequency chattering phenomenon of SM, resulting in reduction of switching losses. In order to verify the sta...
