共射晶体管放大电路中的非綫性反向二极管反饋終于成为組成亳微秒邏輯的一种新途径。在这种电路中利用箝位二极管来得到低的輸入阻抗,避免管子飽和以及获得标准的輸出电压。其瞬变性能及容差計算表明,可以利用这种电路来实現实际的門檻邏輯。对一个具有三个輸入及三个輸出的专門电路进行了測量,其每級的延迟为1.2毫微秒。此外还討論了几个輔助問題,其中包括訊号传送,隔离及設計要求。
The nonlinear diode feedback in the cascode transistor amplification circuit finally becomes a new way of forming the logic of the millivolts. Clamping diodes are used in this circuit to get low input impedance, to avoid tube saturation, and to obtain a standard output voltage. Its transient performance and tolerance calculations show that this circuit can be used to achieve the actual threshold logic. A dedicated circuit with three inputs and three outputs was measured with a delay of 1.2 nanoseconds per stage. Several auxiliary issues were also discussed, including signaling, isolation and design requirements.
