Chapter 19: Problem 4

A circuit technology commonly used to implement designs in FPAAs is (a) switched-inductor circuits (b) emulated resistor networks (c) switched-capacitor circuits (d) AMI

Short Answer

Expert verified
The correct circuit technology commonly used to implement designs in FPAAs is (c) switched-capacitor circuits. This is because they are small, compatible with other analog components, and allow for reconfigurable circuitry.

Step by step solution

01

Rule out incorrect options

To find the correct answer, let's first eliminate the options that are not commonly used for implementing designs in FPAAs. (a) Switched-inductor circuits: Inductors are not typically used in FPAAs due to their large physical size and difficulties in integration. Therefore, this option is not correct. (b) Emulated resistor networks: While resistor networks can be used in FPAAs, they are more commonly implemented in multi-chip modules and not the dominant technology in FPAAs. Therefore, this option is not correct. (d) AMI: This abbreviation stands for Austro-Microsystems International, which is not a circuit technology, thus not applicable to this question. This option is not correct.
02

Identify the correct option

After ruling out the incorrect options mentioned above, we are left with one option that is likely to be the correct answer. (c) Switched-capacitor circuits: These circuits have the advantage of integrating continuous-time functions into an integrated circuit. They are particularly useful in implementing designs in FPAAs due to their small size, compatibility with other analog components, and the ability to reconfigure circuitry for different applications. Therefore, the correct answer to this question is (c) switched-capacitor circuits.
