Abstract: An apparatus includes a digital-to-analog converter (DAC) and an independently controlled biasing circuit coupled to the DAC. The DAC includes at least a first transistor and a second transistor, where the first and second transistors are configured to provide output signals for the DAC. The biasing circuit includes a third transistor having a body coupled to the third transistor source and this source is coupled to a first transistor body and to a second transistor body of the first and second transistors of the DAC. A current loop is coupled to the source and the drain of the transistor of the biasing circuit that maintains a substantially same value of current in the biasing circuit as in the DAC.
