non-inverting amplifier
inverting amplifier
1.The closed gain should be 6dB or higher to prevent the oscillation.
2.When the closed gain is lower than 20dB, use a compensation capacitor (CF: about 5pF),
3.Recommended feedback resistor is less than 2kΩ to keep the flatness of the frequency response.
4.Minimize the load capacitor for the better performance.
1.When the closed gain is lower than 20dB, use a compensation capacitor
2.Minimize the feedback resistor to keep the frequency response and the slew rate.
3.Total load capacitance should be not more than 100pF.
Note:
Unity gain follower application may cause the oscillation.
parallel with the feedback resistor RF to avoid oscillation.
A large load capacitor CL reduces the frequency response and causes oscillation or ringing.
(CF; recommended from 1pF to 5pF), parallel with the feedback resistor RF to avoid oscillation.
(recommended about 1k-ohom)
The proper compensation capacitor CF can counteract oscillation even with a large feedback resistor RF.
The oscillation margin may be affected by the total load capacitance.
