Abstract
Briefly, in accordance with one embodiment of the invention, an integrated circuit includes: a voltage regulator, the voltage regulator having the capability to both sink and source current while maintaining a substantially predetermined voltage level.
Claims17
An integrated circuit comprising:
- a voltage regulator, said voltage regulator having the capability to both sink and source current while maintaining a substantially predetermined voltage level.
A system comprising:
- a driver to transmit data signals along a cable to a receiver, said driver being coupled to a voltage regulator, said voltage regulator having the capability to both sink and source current while maintaining a substantially predetermined voltage level.
A method of both sinking and sourcing current while providing a substantially constant voltage level, said method comprising:
- using a differential pair configuration as a current switch, the differential pair configuration being coupled to provide the substantially constant voltage level as an output signal, the differential pair configuration sinking current from an externally derived current source;
- using at least one of a pair of source follower configurations to source current to the externally derived current source.
