专利内容由知识产权出版社提供专利名称：HIGH EFFICIENCY CURRENT SOURCE/SINKDAC发明人：TUKEL, Suat Sukuti申请号：EP21165530.3申请日：20210329公开号：EP3893397A1公开日：20211013专利附图：摘要：A current source and/or current sink digital-to-analog converter (DAC) includesa DAC circuit that converts a digital code to an analog current or voltage signal, anoptional transconductance circuit that converts a voltage output of the DAC circuit into acurrent signal, and an output circuit that amplifies a current output of the DAC circuit oroptionally amplifies a current output of the transconductance circuit to set a desired highcurrent output for application to an output of the current source and/or current sinkDAC. A power supply control current may be coupled to a power supply circuit thatsupplies power to the output circuit of the current source and/or current sink DAC. Thepower supply control current adjusts the output of the power supply circuit to cause thecurrent source and/or current sink DAC to operate at a higher power efficiency.申请人：Analog Devices International Unlimited Company地址：Bay F1 Raheen Industrial Estate Co.
