The nMOS and pMOS transistors used in BiCMOS is . . . . . . . . A. Depletion mode B. Enhancement mode C. Only pMOS D. Only nMOS

Depletion mode
Enhancement mode
Only pMOS
Only nMOS

The correct answer is: B. Enhancement mode

Explanation:

BiCMOS is a type of integrated circuit that uses both bipolar junction transistors (BJTs) and metal–oxide–semiconductor field-effect transistors (MOSFETs). The nMOS and pMOS transistors used in BiCMOS are enhancement mode transistors. This means that they require a gate voltage greater than a certain threshold voltage in order to turn on.

Depletion mode transistors, on the other hand, do not require a gate voltage to turn on. They are turned on by default, and a gate voltage can be used to turn them off. Depletion mode transistors are not commonly used in BiCMOS circuits.

Only pMOS transistors are not used in BiCMOS circuits. BiCMOS circuits use both nMOS and pMOS transistors.
