Abstract

This article discloses a logic circuit that will operate with low power supply voltages, e.g., in the order of one volt. The one-volt logic (collector drive) circuit shown in Fig. 1 features low Vc voltage (1.0 < Vc < 1.4) requirements _ _ and exhibits a speed of 0.95 nsec. @ 0.35 nwatt (0.33 pico joule). Among its other desirable attributes are: 1) logical NOR configuration 2) collector dottable 3) no current hogging 4) rejection of ground rises 5) 50% conduction Fig. 2 illustrates an alternative one-volt logic (emitter follower driver) circuit. The logical NAND configuration of Fig. 2 offers the same attributes as the NOR configuration shown in Fig. 1.

One-Volt Logic Circuit

This article discloses a logic circuit that will operate with low power supply voltages, e.g., in the order of one volt. The one-volt logic (collector drive) circuit shown in Fig. 1 features low Vc voltage (1.0 < Vc < 1.4) requirements _ _ and exhibits a speed of
0.95 nsec. @ 0.35 nwatt (0.33 pico joule). Among its other desirable attributes are: 1) logical NOR configuration 2) collector dottable
3) no current hogging 4) rejection of ground rises 5) 50% conduction Fig. 2 illustrates an alternative one-volt logic (emitter follower driver) circuit. The logical NAND configuration of Fig. 2 offers the same attributes as the NOR configuration shown in Fig. 1.
