A 200-mA Digital Low Drop-Out Regulator With Coarse-Fine Dual Loop in Mobile Application Processor
Yong-Jin Lee,Wanyuan Qu,Shashank Singh,Dae-Yong Kim,Kwang-Ho Kim,Sang-Ho Kim,Jae-Jin Park,Gyu-Hyeong Cho +7 more
TL;DR: This paper proposes a coarse-fine dual-loop architecture for the digital low drop-out (LDO) regulators with fast transient response and more than 200-mA load capacity and a digital controller is implemented to prevent contentions between the two loops.

A 0.9 V 92 dB Double-Sampled Switched-RC Delta-Sigma Audio ADC
Min Gyu Kim,Gil-Cho Ahn,Pavan Kumar Hanumolu,Sang-Hyeon Lee,Sang-Ho Kim,Seung-Bin You,Jae-Whui Kim,Gabor C. Temes,Un-Ku Moon +8 more
TL;DR: A new method using a combination of a switched-RC technique and a floating switched-capacitor double-sampling configuration enabled low-voltage operation without clock boosting or bootstrapping, and a three-level quantizer with simple dynamic element matching was used to improve linearity.

8.3 A 200mA digital low-drop-out regulator with coarse-fine dual loop in mobile application processors
Yong-Jin Lee,Min-Yong Jung,Shashank Singh,Tae-Hwang Kong,Dae-Yong Kim,Kwang-Ho Kim,Sang-Ho Kim,Jae-Jin Park,Ho-Jin Park,Gyu-Hyeong Cho +9 more
TL;DR: To reduce the number of external capacitors, one power voltage level from the PMIC is converted into a variety of power voltage levels inside the mobile AP and simplifies PCB routes, integrated low-dropout regulators (LDOs) are preferred in mobile APs.

Dual-Path Three-Level Buck Converter With Loop-Free Autocalibration for Flying Capacitor Self-Balancing
Jung Woojoong,Se-Un Shin,Sung-Wan Hong,Sung-Min Yoo,Tae-Hwang Kong,Jun-Hyeok Yang,Sang-Ho Kim,Michael Choi,Jongshin Shin,Hyung-Min Lee +9 more
TL;DR: In this paper, a loop-free autocalibration technique for self-balancing of flying capacitors in a three-level dc-dc buck converter was proposed, which utilizes a dual-path power stage with balancing switches that adaptively short flying capacitor voltages at de-energizing phases.

System and method for performing transmission and reception operations based on broadcast/communication convergence
TL;DR: In this paper, a system for performing transmission and reception operations based on broadcast/communication convergence is proposed, where a transmitter adapted for the broadcast/comunicational convergence converts input broadcast data into a parallel format, inserts port identification (Port ID) information into each of the broadcast data converted into the parallel format and input communication data, multiplexes the broadcast and the communication data and transmits a broadcast and communication convergence signal based on a result of the multiplexing through a single transmission channel.
