1. What is Bandwidth in OPAMP?
Bandwidth in an Operational Amplifier (Op-Amp) refers to the range of frequencies over which the amplifier maintains a consistent gain. It is typically measured up to the frequency where the gain drops to 70.7% (or -3 dB) of its maximum value.
2. What is Slew Rate in OPAMP?
Slew Rate in an Op-Amp is the maximum rate at which the output voltage can change in response to a rapid change in the input signal. It is usually expressed in volts per microsecond (V/µs).
3. What is Frequency Response in OPAMP?
Frequency Response of an Op-Amp describes how the gain of the amplifier changes with respect to frequency. It shows the amplifier’s behavior over a range of frequencies and helps determine its suitability for high-speed or audio applications.
4. What is Inverting Amplifier?
An Inverting Amplifier is a configuration where the input signal is applied to the inverting input of the Op-Amp, and the non-inverting input is grounded. The output is 180 degrees out of phase with the input and the gain is determined by external resistors.
5. What is Non-Inverting Amplifier?
A Non-Inverting Amplifier is a configuration where the input signal is applied to the non-inverting input of the Op-Amp, and the inverting input is connected through a feedback network. The output is in-phase with the input and has a positive gain.
6. What is Voltage Follower Circuit?
A Voltage Follower, also called a buffer amplifier, is a special case of a non-inverting amplifier where the output directly follows the input voltage. It has unity gain and is used to prevent loading effects.
7. What is the Operation of Summing Amplifier?
A Summing Amplifier uses an Op-Amp to add multiple input signals together. When connected in an inverting configuration, it outputs the weighted sum of the input voltages with a negative sign.
8. What is the Operation of Integrating Amplifier?
An Integrating Amplifier outputs the time integral of the input voltage. It uses an Op-Amp with a feedback capacitor and is widely used in analog computers and signal processing.
9. What is the Operation of Differentiator Amplifier?
A Differentiator Amplifier outputs the time derivative of the input voltage. It uses an Op-Amp with an input capacitor and a feedback resistor, converting a changing input into a voltage proportional to its rate of change.
10. What is the Importance of CMRR?
The importance of CMRR (Common Mode Rejection Ratio) lies in its ability to measure how well the Op-Amp can reject common signals on both inputs. A high CMRR is essential in applications requiring high precision and noise immunity, such as instrumentation and sensor interfaces.
