PURPOSE:To obtain a logic integrated circuit with high speed, low power consumption and high yield by constituting all gate circuits except a phase number converting circuit with gate circuits driving a couple of inverting/noninverting phases and outputting a couple of bipolar output signals. CONSTITUTION:In impressing signals with a phase difference of 180 deg. to input terminals I, the inverse of I respectively, the signals are amplified inversely by a differential circuit composing of field effect transistors (FETs) T1, T2 respectively. Then the signals are amplified by a level shift source follower circuit comprising FETs T3, T6 and another level shift source follower circuit composing of FETs T4, T7 and outputted from output terminals Q, -Q. In this case, the signals outputted from the output terminals Q, -Q have a phase difference of 180 deg.. Thus, high speed, low power consumption and high yield are attained. |
