Abstract
A conversion circuit includes a super source follower circuit configured to lower an impedance of a first node. A digital control circuit is configured to adjust a current at the first node based on a current through the super source follower. An output transistor has a gate configured to receive a first signal. A drain of the output transistor is coupled to a first node, and a source of the output transistor is configured to output an output current based on a voltage of the first signal.
