Explanation: The width of the metal 1 layer should be 3 and metal 2 should be 4. When there is no charge on the gate terminal, the drain to source path acts as an open switch. The purpose of defining lambda properly is to make the design itself independent of both process and fabrication and to allow the design to be rescaled at a future date when the fabrication tolerances are shrunk. In the SCMOS rules, circuit geometries are specified in the Mead and Conway's lambda based methodology [1]. Redundant and repetitive information is omitted to make a good artwork system.
