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