Publication number: 20020063582Abstract: A pass-transistor logic circuit configuration that can form a high-speed chip in a small area with short wire length In a selector circuit PMOS and NMOS transistors with different gate signals but with the same drain outputs are arranged, respectively, so their diffusion layers are shared. The PMOS and NMOS are staggered so that their gates are almost in line. With this arrangement, wires connecting drains of the PMOS and NMOS and wires connecting sources of the PMOS and NMOS do not intersect each other, so they can be wired with only the first wiring layer. Further, gate input signals can be wired with only polysilicon wires without crossing each other. The pass-transistor logic circuit is made to pass through the signal buffers before or after it is connected to the selector. This can make a compact, fast circuit.Type: ApplicationFiled: January 23, 2002Publication date: May 30, 2002Inventors: Kunihito Rikino, Yasuhiko Sasaki, Kazuo Yano, Naoki Kato

Patent number: 6388474Abstract: For the relation between the first and second pass-transistor circuits (PT1, PT2), the output signal of the preceding-stage is supplied to the gate of the succeeding-stage, and for the relation between the second and third pass-transistor circuits (PT2, PT3), the output signal of the preceding-stage is supplied to the source-drain path of the succeeding-stage. The first pass-transistor circuit (PT1) receives on its first input node (In1) and second input node (In2) the first input signal and the second input signal that are logically independent from each other. This logic circuit requires a smaller number of transistors and is capable of reducing the power consumption and delay and accomplishing an intricate logic function.Type: GrantFiled: May 21, 2001Date of Patent: May 14, 2002Assignee: Hitachi, Ltd.Inventors: Yasuhiko Sasaki, Kazuo Yano, Shunzo Yamashita, Koichi Seki
