Abstract
A buffer circuit includes a current source circuit, first and second switch circuits that are coupled to the current source circuit, a first resistor coupled to the first switch circuit, a second resistor coupled to the second switch circuit, and a third switch circuit coupled to the first and the second resistors. The third switch circuit couples the first and the second resistors to a node at a first voltage when the buffer circuit is configured to function in a current mode logic buffer mode. The third switch circuit couples the first and the second resistors to a node at a second voltage when the buffer circuit is configured to function in an H-bridge buffer mode.
