ABSTRACT:
A CMOS current steering switch, especially well-suited for use in high speed switching circuits, has a differential switch transistor pair connected to a node, to which a current source is also connected. The gates of the switch transistor pair are controlled by a pair of buffers. The buffers are designed to avoid both switch transistors being off at the same time by decreasing the switching response time on one transistor of the signal compared to the opposite transistor.
