This paper proposes a power-efficient capacitor-array-based digital-to-time converter (DTC) using a constant-slope approach. Fringe-capacitor-based digital-to-analog converter (C-DAC) array is used to regulate starting supply voltage of the constant slope fed to a fixed threshold comparator. The proposed DTC consumes only 15 μW from a 1V supply, while achieving fine resolution of 103 fs when running...
Electric propulsion is thought to be a more effective propulsion system and with government support the number of ships applying this type of system has increased in past years. However the conventional system requires inverter to change propeller revolution, thus making it very complex and expensive. This is because the system is constructed with basic concept that generator engine should be operated...
