Abstract

　ソースドライバ（３－１）において、シフトレジスタ（４）の各ラッチ段では、レベルシフタ（４ａ）がクロック信号（ＳＣＫ、ＳＣＫＢ）をレベルシフトしてセットリセットフリップフロップ（４ｂ）の反転セット入力信号とする。セットリセットフリップフロップ（４ｂ）の出力（Ｑ）を誤動作防止回路（４ｃ）によって遅延して次段のラッチ段のレベルシフタ（４ａ）のイネーブル信号（ＥＮＢ）とする。遅延除去回路（５）は、出力（Ｑ）を遅延回路（５ａ）によって遅延させた出力（Ｑｎ－１’）と、次段のレベルシフタ（４ａ）の出力（ＬＳＢ）とのＮＡＮＤ演算をＮＡＮＤ回路（５ｂ）で行って、サンプリングパルス（ＳＭＰＢ）を導出する。これにより、さらなる出力パルスの遅延除去を行うことができるとともに、出力パルス間の間隔を十分に確保することのできるパルス出力回路を実現する。
