ABSTRACT:
An integrated circuit chip carries a number of electronic circuits, at least one of which includes, in its output stage, a control device that responds to a reference signal to adjust the output current-handling capability of the electronic circuit, thereby regulating the signal propagation delay exhibited by the electronic circuit. The reference circuit is generated by a digital-to-analog circuit that is also formed on the chip. The digital-to-analog circuit is coupled to a number of contact elements disposed on an outer surface of the package containing the integrated circuit chip that can be selectively interconnected to a DC voltage to choose the value of the reference signal.
