Answer: Both NMOS and PMOS transistors complementarily.
- A Mainly NMOS transistors arranged in a push-pull configuration
- B Both NMOS and PMOS transistors complementarily
- C Mainly PMOS transistors arranged in a push-pull configuration
- D Bipolar junction transistors instead of field-effect transistors
Correct answer: B. Both NMOS and PMOS transistors complementarily
Explanation: CMOS (Complementary MOS): NMOS and PMOS in series. When input HIGH: NMOS on, PMOS off, output LOW. Extremely low static power consumption.
Conductors have overlapping bands, semiconductors have a small energy gap that can be bridged by heat or doping, and insulators have a large gap that blocks conduction.
Concept context
Band theory, p-n junction, diodes, transistors, logic gates, and integrated circuits.
