Negative group delay circuit fabricated in an integrated circuit chip

Basic left-handed transmission line (LH-TL) characteristics made on PCB is an important future issue for the application of the EMC field. In this paper, possibility of transmission line with negative group delay characteristic in an integrated circuit is investigated experimentally and numerically. The measured and simulated results demonstrated the usability of the LH-TL. The experimental results indicate some negative group delay characteristic but the differences with the calculation is still existed at higher frequencies.
