Explanation: Usually, IC devices are very small (~1 to 10µm). Even if IC inductor is made in form of a flat metallic thin film spirals. Very small value of the order nanohenry with low quality factor can only be obtained. 12. Which circuit is used to replace inductor in IC components?
A. RC active network
B. PN-junction diode
C. LC active network
D. None of the mentioned
Answer:A

A. RC active network B. PN-junction diode C. LC active network D. None of the mentioned
Explanation: Circuit designer go to great lengths to avoid the use of inductors or otherwise simulate them by using RC active networks. 13. In application such as RF and IF circuits, inductor cannot be avoided. How to manage such situation?
