3. Analog CMOS Circuit Design - Part 1: Design Principles of Operational Amplifiers in CMOS

Try these first

1. 1.

   What is the primary function of an operational amplifier?

   Hint

   Think about signal processing.

2. 2.

   Define input impedance in an op-amp.

   Hint

   Consider how you want it to interact with the source.

3. 3.

   What is the primary purpose of an operational amplifier?

   • A. To multiply signals
   • B. To amplify the difference between input signals
   • C. To convert digital to analog

   Hint

   Think about its function in analog systems.

4. 4.

   True or False: The input impedance of an ideal op-amp should be low.

   • True
   • False

   Hint

   Consider how the op-amp interacts with other circuits.

5. 5.

   Design a CMOS op-amp incorporating all key components discussed and explain how each contributes to achieving high performance.

   Hint

   Make sure to detail how each part interacts within the op-amp.

6. 6.

   Given a set of voltages at the inputs and desire for high gain, optimize the transistor configurations through simulation tools while ensuring low THD and high CMRR.

   Hint

   Utilize the top-down approach and remember to verify results through simulations.
