TL;DR: In this article, a dc-dc buck converter with input voltage ranging from 2.7 to 3.6 V and an output voltage between 1.0 and 1.2 V was fabricated using a standard 0.18-μm CMOS process.

TL;DR: In this article, a switching regulator with quasi-V2 adaptive on-time (AOT) control that provides a fast load transient response is proposed, which makes the switching frequency pseudofixed in the continuous conduction mode and works in the pulse-frequency modulation mode under ultralight load conditions.

TL;DR: A mode-transition technique called duty-lock control is proposed for a digitally controlled NIBB converter that locks the duty cycle and eliminates the error between the output voltage and the reference signal by using a proposed fixed reference scheme that ensures the stability of the digital controller and output voltage.

TL;DR: An enhanced duty-cycle-overlap control technique for a digitally controlled NIBB converter that offers two duty cycle limitations for various conditions in the mode-transition region and ensures the stability of the digital controller and output voltage.

TL;DR: Under ultralight load conditions, the proposed converter operates in a pulse frequency modulation mode to reduce the switching loss and improve light load efficiency and a quasi- V2 technique is applied for obtaining inductor current information without relying on an output capacitor with a high equivalent series resistance.
