Abstract

This disclosure describes a precise, fast, and relatively low power current-source for use in various applications, which may include driving power semiconductors such power MOSFETs and IGBTs. The current-source may provide both a constant current and a current profile over time which may charge and discharge the steering terminal (e.g. the gate) of a power semiconductor for precise control of switch timing. The current-source uses current steering digital-to-analog converter (DAC) technology and current mirrors to generate a high output current that is significantly immune to power supply and ground variability.
