PULSE SYNTHESIZING CIRCUIT

摘要

A circuit having versatility synthesizes one-bit digital signals to generate a ternary signal. The pulse synthesizing circuit synthesizes one-bit digital signals from two DFFs to generate a ternary signal. The pulse synthesizing circuit has a first NOR gate, a second NOR gate, a third NOR gate, and three switches. The first switch is connected to a first electric potential, the second switch is connected to a second electric potential, and the third switch is connected to a third electric potential. The first to third switches are turned on/off according to logical values of the signals from the two DFFs, and any of the first electric potential, the second electric potential, and the third electric potential is set as an output potential so that a ternary signal is generated.

1. A pulse synthesizing circuit for synthesizing a first one-bit digital signal and a second one-bit digital signal to generate a ternary signal, the circuit comprising:
a logic circuit for outputting a first electric potential in a first case of a combination of a logical value of the first one-bit digital signal and a logical value of the second one-bit digital signal, outputting a second electric potential smaller than the first electric potential in a second case where a combination of a logical value of the first one-bit digital signal and a logical value of the second one-bit digital signal is different from the combination in the first case, and outputting a third electric potential between the first electric potential and the second electric potential in a third case where a combination of a logical value of the first one-bit digital signal and a logical value of the second one-bit digital signal is different from the combinations in the first case and the second case.
