    • The present invention relates to a complementary transistor circuit and an amplifier using it, and, in particular, to a video amplifier for amplifying video signals and a high-definition CRT display device. In amplifying inputted video signals by using a multiplexer, a gain controller and a current mirror amplifier, each element circuit is formed by using complementary transistor circuits. Circuit simplification is thus attained. In addition, higher precision and band broadening has been realized owing to adoption of a current operation. Further, the present invention makes it possible to eliminate direct feedback from the high voltage output completely by providing a low-voltage output circuit for feedback having a similar relationship with respect to the high-voltage video output stage of the video amplifier, thereby performing negative feedback via a sample-and-hold circuit. This also serves to broaden the bandwidth and reduce power dissipation.
    • 互补晶体管电路及其放大器技术领域本发明涉及互补晶体管电路及其使用的放大器,特别涉及用于放大视频信号的视频放大器和高分辨率CRT显示装置。 通过使用多路复用器,增益控制器和电流镜放大器来放大输入的视频信号,通过使用互补晶体管电路形成每个元件电路。 因此实现了电路简化。 此外,由于采用了当前的操作,已经实现了更高的精度和频带扩展。 此外,本发明通过提供与视频放大器的高电压视频输出级具有类似关系的反馈的低电压输出电路,可以完全消除来自高电压输出的直接反馈,由此执行负 通过采样保持电路进行反馈。 这也有助于扩大带宽并降低功耗。
