2.2. Parameters

Try these first

1. 1.

   What does the Input Offset Voltage indicate?

   Hint

   Think about balancing inputs.

2. 2.

   Define Input Bias Current.

   Hint

   Consider its effect on high impedance setups.

3. 3.

   What is the purpose of the Input Offset Voltage?

   • To amplify signals
   • To provide zero output
   • To stabilize power

   Hint

   Consider what happens when input signals are equal.

4. 4.

   CMRR measures the ability to reject?

   • True
   • False

   Hint

   Think about noise and interference.

5. 5.

   In a sensitive measurement system utilizing an Op-Amp, the Input Offset Voltage is reported to be 5mV. Discuss potential implications on measurement accuracy and suggest how to mitigate errors.

   Hint

   Consider what the measured output should ideally be.

6. 6.

   A circuit using an Op-Amp has a Slew Rate of 0.5 V/µs. If an input signal changes by 10V in a microsecond, illustrate what the output signal might look like, and clarify why this is a concern.

   Hint

   Sketch the ideal output versus the actual output pattern.
