摘要： A digital data transmitting device is disclosed having differential signaling circuitry, a current source controller and a pair of transistor-implemented current sources is disclosed. The current source controller generates a current source control signal based on a detected mode of operation of the differential signaling circuitry. The pair of transistor-implemented current sources selectively generate source currents to adjust the output voltage levels as the differential output terminals in response to the current source control signal. The digital data transmitting device may also include a current bulk biasing circuit that generates a current source bulk biasing signal such that when the differential signaling circuitry is in one mode of operation, the current source bulk biasing signal retards currents leakage across the pair of transistor-implemented current sources.
