A single-stage LED driver based on interleaved buck-boost circuit and LLC resonant converter is proposed. The buck-boost circuit and LLC resonant converter are integrated by sharing switches, which can decrease the system cost and improve system efficiency. The input voltage of the buck-boost circuit is half of the rectified voltage, and two buckboost circuits are formed with the two half-bridg...

متن کاملAn On-Chip Clock Jitter Fault Detection Circuit for System-on-Chip Application
Clock jitter has become a problem for integrating IP cores and peripheral devices into a single synchronous SoC. In this paper, we propose an on-chip clock jitter detect circuit to enhance design flexibility, which only consists of twelve transistors and two minor capacitors. The proposed circuit transforms the clock jitter error to deviation of voltage (TVC) but has no use of constant current ...
