  • High-speed DAC
    Patent number: 10498351
    Abstract: A digital-to-analog converter (“DAC”) system for converting a digital input code to an analog signal, comprises: an N-bit DAC and a back-gate bias generator (“BBGEN”). The N-bit DAC has a reference cell and a current source array of unit cells for generating a DAC output. The (“BBGEN”) generates a first back-gate bias voltage PB_CSM and a second back-gate bias voltage PB_CSA. A back gate of the reference cell is configured to receive the first back-gate bias voltage PB_CSM. A back gate of each of the unit cells is configured to receive the second back-gate bias voltage PB_CSA. The reference cell is configured to generate a main current, and the unit cells are configured to mirror the main current.
