Logic circuit
专利汇可以提供Logic circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To increase an operating speed by making the voltage of a power source supplied to a transistor with which an output terminal and a drain electrode are connected higher than the voltage of the power source supplied to the transistors except for the transistor and making the gate length of the transistor longer than those of the other transistors.
CONSTITUTION: Parasitic capacities 43 and 44 which are further larger than the capacities charged and discharged by transistors(Tr) 11-15, and 21-25, are added to output terminals 33 and 34. However, a VDD 2 101 on 5.0V which is higher than a VDD 11 on 3.3V is impressed to the sources of Tr 116 and 117, so that the drain currents of the Tr 116 and 117 can be larger than the drain currents of the Tr 11-15. and 21-25 with the same gate width, and therefore, the capacities added to the output terminals can be charged at a high speed. Thus, the dependency of the load capacities of a logic circuit can be sharply improved, and an integrated circuit device can be operated at the high speed.
