A new low-swing pass-transistor logic style for designing high-performance crossbar switches for system-on-chip applications is proposed. The new passtransistor architecture uses current-switching and end-to end swing restoration to improve the crossbar performance. The architecture is verified in 0.35 and 0.25 ?m CMOS technology. The 4-b 4?4 crossbar switch in 0.35 ?m CMOS occupied an area of 1.4 ?m2 and achieved 36 Gb/s. Analysis suggests that the new logic style can be used to design multi-Tb/s crossbar switches in 0.18 ?m and lower CMOS technology.
