PHASE SPLITTER

摘要

PURPOSE: An identical delay and converted phase buffer is provided to reduce the number of a compositing device when panning out is increased. CONSTITUTION: The buffer includes a delay and conversion delay portions(10), pull up and pull down portions(20) and an outputting portion(30). The delay and conversion delay portions output a conversion delay output signal converted and delayed an input signal and a non-conversion delay output signal delayed the input signal so as to have a state a high voltage and a ground voltage whose voltage value is larger than a power voltage. The pull up and pull down portions receive the conversion delay output signal and the non-conversion delay output signal of the delay and conversion delay portion and output an output signal, which is the same a phase as the input signal and is delayed during a predetermined time, having a state of a low voltage whose voltage value is lower than that of the high voltage and the ground voltage. The outputting portion outputs an output signal having a state of a power voltage and a ground voltage by converting and delaying an output signal of the pull up and pull down portion and an output signal having a state of the power voltage and the ground voltage by delaying the output signal of the pull up and pull down portion.
