Design automation with the TSPC circuit technique: ahigh-performance wave digital filter

摘要

In this paper, we demonstrate how the true single-phase clockingn(TSPC) circuit technique is utilized fur a high-speed recursive filternapplication, with a high degree of design automation. This features anquick netlist generation of integral high-speed arithmetic modules,nutilization of carry-save architectures, and synthesis and optimizationnwith a TSPC cell library. Implementation results in a 0.8 Μm standardnCMOS process indicate substantial performance improvements overntraditional designs, at the same time keeping design time very short.nFabricated samples of the third-order lattice wave digital filter werenmeasured at 265 Msamples/s, which is more than double the sample ratenreported in previous works on the same filter and same or comparablentechnology
