Abstract:
A current-steering digital-to-analog converter may include a plurality of current cells. Each current cell may comprise a dual bias switched cascode output current source/sink, a bias source, complementary bias switching elements coupled between the bias source and the bias inputs of the switched cascode output current source/sink, and complementary switching signals coupled to the control inputs of the complementary bias switching element.
