Current-Balanced Logic in Submicron Technology

The analysis of the current-balanced logic (CBL) in submicron technology is presented. Current-balanced logic is a low-noise logic family suitable for use in mixed-signal integrated circuits, because of the reduced supply current spikes. Entering the submicron region the question arises whether the CBL will still preserve the mentioned good performances. The analysis of CBL with the simple current model of the submicron MOS transistor was carried out. The supply current is not fully compensated, but the deviation is not too high. The current spikes are still lower than in CMOS. The variation of the supply current in the CBL was verified with the SPICE simulation of the CBL inverter in the 0.25-*m technology. SPICE simulations were also used to compare the static and ddynamic performances of the CBL and the CMOS inverters. *=micro
