Inductive current digital-to-analog converter with inductor current control

A recently granted US patent (Publication Number: US12003251B2) discloses an inductive current digital-to-analog converter (DAC) featuring an inductor with control circuitry, phase selection circuit, and driver circuit. The inductor current control circuitry includes sense circuitry and comparison circuitry to regulate the inductor current. The set of switches in the DAC allows for different configurations to control the flow of current through the inductor, enabling precise operation.
Furthermore, the patent details a control circuit coupled to field-effect transistors (FETs) in the DAC, facilitating the management of different phases such as magnetization, output, and energy storage. The control circuit is designed to adjust the inductor current thresholds based on control codes and load control signals, catering to various loads like optical transmitters, proximity sensors, and range sensors. This innovative DAC design offers flexibility and adaptability in timing and phase selection, enhancing its utility across a range of applications requiring accurate current control and modulation.
