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 7):
The DAC system of  claim 6 ,\n wherein the bandgap circuit is coupled to an input of the V2I circuit for providing a band gap voltage to the V2I circuit, wherein the V2I circuit is coupled to a resistor and the reference cell for generating a current through the reference cell based on the bandgap voltage and a resistance of the resistor, wherein the reference cell is coupled to the current source array for generating a differential, analog output signal, wherein the registers are configured to store the digital input code, and wherein the registers, decoder, deglitch and level shifter, and the clock tree are coupled together to generate differential signals to operate switches of the unit cells.
