New design of differential transmission lines on silicon

Transmission lines (TLs) have been used as part of resonators, filters, and similar modules for many years. But the electrical length of these TLs is in the range between lambda/8 and lambda mostly. Thus these lines had not been used for monolithic integration on silicon so far because of their exorbitant area usage. This paper demonstrates dramatically area shrinked differential TLs (DTLs) due to changed line configuration and added capacitors. At the same time the Q-factor could be improved in same magnitude. Now DTLs are ready for use in monolithic integration on silicon
