Original Abstract Submitted
A single ended driver circuit () for a digital to analog conversion, DAC, cell is presented. The driver circuit () comprises one positive single-edge latch () configured to provide a positive edge latched data signal (S) by latching a positive edge of a data signal (D) synchronized by a first clock signal (CLK), and a negative single-edge latch () configured to provide a negative edge latched data signal (S) by latching a negative edge of the data signal (D) synchronized by a second clock signal (CLK). The positive edge latched data signal (S) and the negative edge latched data signal (S) are combined to provide a drive signal (S) having a positive edge synchronized by the first clock signal (CLK) and a negative edge synchronized by the second clock signal (CLK). The positive single-edge latch () and the negative single-edge latch () are also presented.
