Abstract
An integrated circuit includes at least one main circuitoperable to perform one or more functions. At least one termination node DQ receives or transmits an operating signal. An active termination circuithas first and second transistors of opposite type coupled in series between a Vdd node of a first source potential and a Vss node of a second source potential. The at least one termination node is coupled to a common node between the first and second transistors. A control circuit operates to bias the first and second transistors such that they exhibit a controlled impedance at the common node. Alternatively, the control circuit operates to bias the first and second transistors such that they provide a clamping function at the common node.
