在电量和非电量的数字测量技术中,控制电路是一个各显巧妙的主要组成部分。本文在简要的分析了控制电路的基本功能后,对CMOS集成电路中的两种具有较好控制性能的触发器(主从D触发器—CO43和JK主从触发器—CO44)所组成的控制电路的工作原理作了简要的分析介绍,内容包括:用单块CO43和CO44所组成的测量频率和周期的控制电路;用单块CO43和CO44组成的测时控制电路;用单块CO43和CO44组成的由双端控制的测量控制电路;以及用两种IC块组成的控制显示时间和发出清零信号的延时电路。本文所介绍的各个电路,部分已在工作中应用,其余也已经实验验证。
In both digital and non-digital measurement techniques, the control circuit is an ingenious integral part of each. After a brief analysis of the basic functions of the control circuit, the control of two kinds of flip-flop with good control performance (master-slave D flip-flop-CO43 and JK master-slave flip-flop-CO44) in the CMOS integrated circuit The working principle of the circuit made a brief analysis and introduction, including: control circuit with a single CO43 and CO44 measuring frequency and cycle; with a single CO43 and CO44 timing control circuit; with a single CO43 and CO44 Composed of double-ended control of the measurement and control circuits; and composed of two kinds of IC blocks to control the display time and send clear signal delay circuit. This article describes the various circuits, part of the work has been applied, the rest have been experimentally verified.
