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.

Claim (Index 5):
The DAC system of  claim 4 , wherein each of the unit cells comprises:\n a third transistor; a fourth transistor; and a switch for connecting the respective unit cell to either the first output node or the second output node, wherein the third transistor and the fourth transistor are serially connected for generating a current to mirror the main current, wherein the third transistor has a back-gate configured to receive the second back-gate bias voltage PB_CSA, wherein a gate of the third transistor is coupled to a gate of the first transistor, and wherein a gate of the fourth transistor is coupled to a gate of the second transistor.
