Multiple choice physics semiconductors integrated circuits & microprocessor integrated chips semiconductor devices

Which of the following is not a type of an IC?

  1. Analog IC

  2. Digital IC

  3. Mixed IC

  4. Compound IC
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Analog circuits are circuits dealing with signals free to vary from zero to full power supply voltage. This stands in contrast to digital circuits, which almost exclusively employ “all or nothing” signals.
A mixed integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor device.
