Abstract

Systems and methods according to one or more embodiments provide a low power current steering digital-to-analog converter. In one example, a device includes a current cell including a plurality of switches. The device further includes a current cell controller configured to selectively operate the plurality of switches. The plurality of switches is selectively operated to cause the current cell to generate a current signal in response to a first data signal. The plurality of switches is selectively operated to disable the current cell in an absence of the first data signal. The plurality of switches is selectively operated to transition the current cell to a common mode state before the current cell receives the first data signal. Related systems and methods are also provided.
