Methods and systems are described for receiving a control step input at a binary-to-thermometer decoder and responsively generating bits of a thermometer codeword representative of the control step input, providing the bits of the thermometer codeword to a plurality of differential pairs comprising a first transistor and a second transistor, each differential pair configurable for one of directing current to an in-phase (I) common node or directing current to a quadrature phase (Q) common node and switching between directing current to the I common node and the Q common node, and forming an output signal based on current drawn through the I and Q common nodes, the output signal having an intermediate phase with respect to a first and a second reference signal.
