Abstract:
1. A complementary signal generator for outputting complementary positive-phase and antiphase signals that vary between a first logical value and a second logical value, comprising: a signal forming unit for outputting a positive-phase intermediate signal being in phase with an input signal varying between the first logical value and the second logical value to a positive-phase intermediate node, and an antiphase intermediate signal antiphase to the input signal to an antiphase intermediate node; a positive-phase signal output part; an antiphase signal output part; a first connecting means connected among the positive-phase intermediate node, the antiphase intermediate note, the positive-phase signal output part, and the antiphase signal output part and having a first control terminal for receiving a first control signal produced in synchronism with a state change of the input signal from the first logical value to the second logical value, and for simultaneously transferring the second logical value of the positive-phase intermediate signal and the first logical value of the antiphase intermediate signal to the positive-phase signal output part and the antiphase signal output part respectively; and a driving means for individually setting respective states of the positive-phase signal output part and the antiphase signal output part to the first logical value and the second logical value.
