Current-Mode Logic (CML) and low-power Complementary Metal-Oxide-Semiconductor (CMOS) technology continue to drive significant advances in digital circuit design, particularly in high-speed and energy ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...
