Question
Which of the following is an advantage of BiCMOS logic?
Answer Options
- A) Its simplicity results in much less expensive devices than standard CMOS
- B) It is immune to electrostatic damage
- C) It has the high input impedance of CMOS and the low output impedance of bipolar transistors
- D) All these choices are correct
Correct Answer: C
Explanation
BiCMOS is a hybrid integrated circuit technology that combines Bipolar Junction Transistors (BJTs) and CMOS (Complementary Metal-Oxide-Semiconductor) field-effect transistors onto the same monolithic chip. This combination aims to capitalize on the best characteristics of both technologies.
The key advantage of BiCMOS logic is that it has the high input impedance of CMOS and the low output impedance (high current drive capability) of bipolar transistors. This pairing allows for inputs that draw negligible current (low power consumption) and outputs that can drive large loads at high speed, making BiCMOS ICs excellent for fast memory and high-current driver applications.
