Abstract
As disclosed herein, a microelectronic circuit and method are provided for improving signal integrity at a transmission line. The circuit includes a programmably adjustable impedance matching circuit which is coupled to a transmission line which includes a programmably adjustable inductive element. The programmably adjustable impedance matching circuit is desirably provided on the same chip as a receiver or transmitter to which the transmission line is coupled, or alternatively, on an element packaged together with the chip that includes the receiver or transmitter. The impedance of the programmably adjustable impedance matching circuit is adjustable in response to control input to improve signal integrity at the transmission line.
