摘要:
A digital-to-analog converter is provided. The digital-to-analog converter includes a plurality of digital-to-analog converter cells coupled to an output node of the digital-to-analog converter. At least one of the plurality of digital-to-analog converter cells includes a capacitive element configured to provide an analog output signal of the digital-to-analog converter cell to the output node. Further, the at least one of the plurality of digital-to-analog converter cells includes an inverter circuit coupled to the capacitive element. The inverter circuit is configured to generate an inverter signal for the capacitive element based on an oscillation signal. The at least one of the plurality of digital-to-analog converter cells additionally includes a resistive element coupled to the inverter circuit and the capacitive element. A resistance of the resistive element is at least 50Ω.
