Senior Physical Design Engineer Interview Questions and Answers

CMOS devices are the building blocks of digital circuits, consisting of a PMOS and an NMOS transistor.

• CMOS stands for Complementary Metal-Oxide-Semiconductor

• PMOS and NMOS transistors are used to create logic gates

• CMOS devices have low power consumption and high noise immunity

• The operation of a CMOS device involves charging and discharging the gate capacitance to control the flow of current

• The output of a CMOS device is either high or low, depending on the input voltage levels
