基于开关信号理论 ,本文对ECL电路中的阈值控制进行了研究 ,建立了用于描述施密特电路中阈值可控开关工作过程的数学表示式。在此基础上设计了具有二次跳阈反应的三值ECL施密特电路。对所设计电路的PSPICE模拟表明它具有理想的施密特电路特性
Based on the switching signal theory, this paper studies the threshold control in the ECL circuit, and establishes the mathematical expression used to describe the working process of the threshold controllable switch in the Schmitt circuit. Based on this, a three-value ECL Schmitt circuit with double jump threshold is designed. PSPICE simulation of the circuit design shows that it has the ideal Schmitt circuit characteristics
