A Fully Synthesizable Fractional-N MDLL With Zero-Order Interpolation-Based DTC Nonlinearity Calibration and Two-Step Hybrid Phase Offset Calibration

In this paper, a fully-synthesizable digital-to-time (DTC)-based fractional-N multiplying delay-locked loop,(MDLL) is presented. Noise and linearity of synthesizable DTCs are analyzed, and a two-stage synthesizable DTC is proposed in which a path-selection DTC is used as the coarse stage and a variable-slope DTC is used as the fine stage. To...

Design of an Isolated Converter for Cable-free PV Modules

Climate change has called for an urgent revolution in our energy sector. Concerning energy generation, the use of fossil fuels must be decreased, due to the carbon pollution they produce, and more and more green energy is required to be integrated into the power system. Solar energy represents a valid alternative to generates electricity without...
