Abstract
A method and system are directed to designing a low-dropout regulator (LDO) circuit and using the LDO circuit to detect recycled counterfeit integrated circuits. The LDO circuit includes, in part, a reference path circuit and a stressed path circuit. Each of the reference path circuit and the stressed path circuit is coupled to a control signal that can enable the corresponding path circuit for the LDO. LDO parameters can then be measured while the reference path circuit and the stressed path circuit is enabled respectively. The difference between the LDO parameters measured while the reference path circuit is enabled and while the stressed path circuit is enabled is used to determine if an integrated circuit comprising the LDO circuit is a recycled counterfeit.
