Note: Attempt any seven questions. All questions carry equal marks. Use of scientific calculator is permitted. Missing data if any, may be suitably assumed.
1. Give the circuit diagram of a BJT based Wilson current source and derive an expression for its output current and output resistance.
2. What is the function of a level-translator circuit? Draw the circuit diagram of any level-translator circuit and explain its operation with the help of necessary mathematical steps. 3+7=10
3. Derive an expression for the total output offset voltage of an op-amp. Also, explain the effect of temperature on it. 5+5=10
4. Define the following terms
Input offset voltage, Input bias current, Input offset current, SVRR and CMRR. 5x2=10
5. Define the term Slew rate. What are the causes of Slew rate in op-amp Also, explain its effect on anyone application.
