A fully-integrated active matrix light-emitting diode (AMLED) micro display system is presented. The system consists of a 36×64 pixel-drivers encompassed by a fully on-chip hybrid voltage regulator built on the same silicon chip, then integrated with the AMLED array by using the flip-chip bonding technology. As such, no external passive component is needed. The hybrid voltage regulator consists of...
An adaptive threshold decoding algorithm is proposed for recovering visible light communication signals transmitted by a LED-based display. The measured BER of data received from a 4-frame/s micro-LED display is improved from 6.9×10−2 to 4.4×10−4 using the proposed algorithm compared to conventional constant threshold scheme.
This paper analyzes and designs inductive coupling power delivery (ICPD) system for 3-D stacked chips in SMIC 65-nm CMOS process. Two shapes of inductors, the rectangular and the octagonal inductor, are compared. Fully customized octagonal inductors with 500 μm diameter are optimized to improve power delivery efficiency. An octagonal inductor based ICPD consisting transmitter and receiver circuit...
A high frequency, high power density wireless interchip power delivery for 3-D Stacked chips applications is proposed and implemented in SMIC 65-nm CMOS process. To achieve high operating frequency — 1 GHz, a frequency multiplication circuit is proposed. A capacitive compensation in transmitter side is used to improve the power delivery performance in Series-Paralled topology based on the principle...
