Abstract
A~~t~a~~ --- A novel asynchronous timing scheme, ata-driven self-timing (DDST) is proposed and imple-Flux-Quantum (RSFQ) superircuits. In this asynchronous als are generated from the data ded to drive the RSFQ circuit the self-timing scheme is to g in order to avoid the overhead ion, and to minimize the timing scheme has been applied to the register, a demultiplexor, and a selfst system. In this paper, test register and a high speed onerator will be presented to demonstrate the ST operation of RSFQ integrated circuits at a rate of 20 Gbk.
