Most LDO regulators before are off-chip so that they are hard to meet the demands of SOC solutions. This thesis is target on SOC applications and analyzes the challenges of stability, transient regulation and line regulation, etc. Trade-off relations between different characterizations are seriously discussed. In order to meet the demand of high precision and self-stability, a newly LDO structure is proposed and design process is carefully described, which manifest many design points. A PMOS is chosen to be the output transistor of this on-chip LDO. To maintain stability, miller capacitor in serious with nulling resistor is used.

The model in this paper takes the form as belowThe main contents and results in this paper are as follows:In section 1, we state our main analytical results on equilibria of the above system. First, several sufficient conditions for coexistence of the steady-state are given by the standard fixed-point index theory in cone. Second, the global structure of the coexistence solutions and their local stability are established by using bifurcation theory. Third, the multiplicity, uniqueness and stability of positive steady-state solutions to this system are derived by means of perturbation theory of eigenvalues, standard regularity theory, Sobolev embedding theorem and fixed-point index theory.
