The Logic AND Gate is a type of digital logic circuit whose output goes HIGH to a logic level 1 only when all of its inputs are HIGH. The output state of a digital logic AND gate only returns “LOW” again when ANY of its inputs are at a logic level “0”. In other words for a logic AND gate, any LOW input will give ...A CMOS is fabricated on a substrate that acts as an electrical reference and gives mechanical support.

P/N ratios apply to other static CMOS gates besides inverters. For example, a normal skew NAND2 gate uses equal sized NMOS and PMOS transistors because the NMOS are in series. A high-skew NAND2 doubles the PMOS width, while a low-skew NAND2 doubles the NMOS width. Similarly, a normal skew NOR2 gate uses PMOS transistors four times the NMOS width.Gate-source voltage V GS 1/κ Drain-source voltage V DS 1/κ Threshold voltage V TH 1/κ Doping concentration N A, N D κ Table 1.2 Scaling results for device characteristics.
