This paper presents the implementation and performance analysis of a self clocked Asynchronous DLDO without an external capacitor. The proposed DLDO architecture includes Logic-Threshold Triggered Comparator (LTTC) for voltage quantization and a Self-Shift Bi-directional Shift Registers (SS-BiSHRs) for internal clock generation. Additionally, a Unary Binary Scheme (UBS) is applied to the power transistor array to optimize both transient response and steady-state accuracy. Simulation result shows a load transient response 0.3us with an undershoot of 191.6mV and a quiescent current of 35.4μA at V<sub>DD</sub> 0.7V.
