摘要：A design structure, structure, and method for providing an on-chip variable

delay transmission line with a fixed characteristic impedance. A method of manufacturinga transmission line structure includes forming a signal line of the transmission linestructure, forming a first ground return structure that causes a first delay and a firstcharacteristic impedance in the transmission line structure, and forming a second groundreturn structure that causes a second delay and a second characteristic impedance in thetransmission line structure. The first delay is different from the second delay, and thefirst characteristic impedance is substantially the same as the second characteristicimpedance.
