Complementary Metal-Oxide-Semiconductor (CMOS) technology is a vital part of modern electronics, used in designing and manufacturing integrated circuits (ICs) that power many digital devices. CMOS ...

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 ...
