Hi,
I chose 5V as the INA118 supply for an input common mode of 3.3V and I think the input is in the operating range. I am including my schematic in here. What I am trying to do is a High side current sense of an IC. Rx is chosen such that when the…
Hello Hari,
For the complete story regarding dual-feedback stability analysis see the attached PowerPoint. Slides 100 through 114 are specifically about op amp dual-feedback stability analysis.
This stability slide content was developed by Tim Green…

This may help. It is an old (2000) presentation that I made to the Burr-Brown Field Applications Engineers (pre-TI acquisition) about using op amps as comparators.
It contains bench test data on op amps that were popular at that time…
Connecting a capacitor on the output of an op amp can often lead to oscillations instead of the expected response. Also, the amplifier feedback resistors can interact with the amplifier input capacitance causing oscillations. These issues are called op…
Hi Jorge,
When deciding which circuit configuration to choose, the designer has to consider a number of factors, for example, you will have to consider the amplifier stability driving the capacitive load, the size of the RISO resistor required to stabilize…
Other Parts Discussed in Thread: 4213 The attached presentation details how to make many common op amp circuits stable.

Hi Nishanth,
I would recommend you go through the TI precision labs series on op amp stability found here:
Additionally, you may find this stability presentation useful: 3175.Solving Op Amp Stability 2015_TG.pptx
This should give you everything…
Hi Byliu,
Can you please describe the issues you are having? When I run the file you have provided I do not run into convergence issues.
Composite amplifiers are generally used when you need an amplifier with good dc precision and either strong drive…
