Abstract
In one example, a current steering circuit includes an output transistor pair responsive to a first gate bias voltage. The current steering circuit further includes a first switch comprising a first source-coupled transistor pair coupled to the output transistor pair and responsive to a first differential gate voltage, and a second switch comprising a second source-coupled transistor pair coupled to the output transistor pair and responsive to a second differential gate voltage. The current steering circuit further includes a current source configured to source a bias current. The current steering circuit further includes a third switch comprising a third source-coupled transistor pair coupled between the current source and each of the first switch and the second switch, the third source-coupled transistor pair responsive to a third differential gate voltage.
