Original Abstract Submitted
Certain aspects of the present disclosure generally relate to a digital-to-analog converter (DAC) circuit implemented with a dynamic stacked transistor architecture. The DAC circuit generally includes a first current-steering transistor and a second current-steering transistor. The DAC circuit may also include: a first stacked transistor coupled between the first current-steering transistor and a first output of the DAC circuit; a first switch coupled between a gate of the first stacked transistor and a bias voltage node; a second switch coupled between the gate of the first stacked transistor and a voltage rail; a second stacked transistor coupled between the second current-steering transistor and a second output of the DAC circuit; a third switch coupled between a gate of the second stacked transistor and the bias voltage node; and a fourth switch coupled between the gate of the second stacked transistor and the voltage rail.
