Patent ID: 8610609

Claim:
A digital-to-analog converter (DAC), comprising: a latch circuit comprising: an n-type metal-oxide-semiconductor (NMOS) field effect transistor-based buffer, the latch circuit capable of receiving a first digital signal and a clock signal and outputting a second digital signal through the NMOS field effect transistor-based buffer according to the clock signal, the second digital signal being associated with the first digital signal; and a latch that receives the first digital signal and the clock signal and outputs, according to the clock signal, the first digital signal and an inverse first digital signal that is an inverse of the first digital signal, wherein the NMOS field effect transistor-based buffer is coupled to receive the first digital signal and the inverse first digital signal from the latch and output a buffered first digital signal and a buffered inverse first digital signal that is an inverse of the buffered first digital signal, one of the buffered first digital signal and the buffered inverse first digital signal being the second digital signal; and a unit cell circuit, coupled to the latch circuit, that receives the second digital signal and outputs an analog signal representative of the first digital signal.
