ABSTRACT:
A method and apparatus are provided for bidirectional current conduction between first and second nodes of an electronic circuit. A first substantially constant current is conducted through a first current mirror pair of transistors coupled between the first and second nodes, in a first direction away from the first node toward the second node, in response to the first node having a voltage higher than the second node. A second substantially constant current is conducted through a second current mirror pair of transistors coupled between the first and second nodes, in a second direction away from the second node toward the first node, in response to the first node having a voltage lower than the second node.
